Fuel Arithmetic

1A lorry has 28 litres of fuel in its tank. An additional 75 litres is filled. What is the total quantity of fuel in the lorry?Show solution
Given: Fuel already in tank = 28 l; Fuel added = 75 l

We need to find the total quantity of fuel.

28+7528 + 75

Step 1: Add the ones digits: 8+5=138 + 5 = 13. Write 3, carry 1.

Step 2: Add the tens digits: 2+7+1(carry)=102 + 7 + 1\text{(carry)} = 10. Write 10.

28+75=10328 + 75 = 103

The total quantity of fuel in the lorry is 103 litres.

2Find the sum of 49 and 89.Show solution
Given: Two numbers are 49 and 89.

49+8949 + 89

Step 1: Add the ones digits: 9+9=189 + 9 = 18. Write 8, carry 1.

Step 2: Add the tens digits: 4+8+1(carry)=134 + 8 + 1\text{(carry)} = 13. Write 13.

49+89=13849 + 89 = 138

The sum of 49 and 89 is 138.

Relationship Between Addition and Subtraction

1Find the relationship between the numbers in the given statements and fill in the blanks appropriately.
(a) If 46 + 21 = 67, then 67 − 21 = ______ and 67 − 46 = ______.
(b) If 198 − 98 = 100, then 100 + ______ = 198 and 198 − ______ = 98.
(c) If 189 + 98 = 287, then 287 − 98 = ______ and 287 − 189 = ______.
(d) If 872 − 672 = 200, then 200 + ______ = 872 and 872 − ______ = 672.Show solution
Concept: Addition and subtraction are inverse operations. If a+b=ca + b = c, then c−b=ac - b = a and c−a=bc - a = b. If a−b=ca - b = c, then c+b=ac + b = a and a−c=ba - c = b.

(a) If 46+21=6746 + 21 = 67, then:
- 67−21=4667 - 21 = \mathbf{46}
- 67−46=2167 - 46 = \mathbf{21}

(b) If 198−98=100198 - 98 = 100, then:
- 100+98=198100 + \mathbf{98} = 198
- 198−100=98198 - \mathbf{100} = 98

(c) If 189+98=287189 + 98 = 287, then:
- 287−98=189287 - 98 = \mathbf{189}
- 287−189=98287 - 189 = \mathbf{98}

(d) If 872−672=200872 - 672 = 200, then:
- 200+672=872200 + \mathbf{672} = 872
- 872−200=672872 - \mathbf{200} = 672

2In each of the following, write the subtraction and addition sentences that follow from the given sentence.
(a) If 78 + 164 = 242, then __________.
(b) If 462 + 839 = 1301, then __________.
(c) If 921 − 137 = 784, then __________.
(d) If 824 − 234 = 590, then __________.Show solution
Concept: From any addition fact a+b=ca + b = c, we get c−b=ac - b = a and c−a=bc - a = b. From any subtraction fact a−b=ca - b = c, we get c+b=ac + b = a and a−c=ba - c = b.

(a) If 78+164=24278 + 164 = 242, then:
242−164=78and242−78=164242 - 164 = 78 \quad \text{and} \quad 242 - 78 = 164

(b) If 462+839=1301462 + 839 = 1301, then:
1301−839=462and1301−462=8391301 - 839 = 462 \quad \text{and} \quad 1301 - 462 = 839

(c) If 921−137=784921 - 137 = 784, then:
784+137=921and921−784=137784 + 137 = 921 \quad \text{and} \quad 921 - 784 = 137

(d) If 824−234=590824 - 234 = 590, then:
590+234=824and824−590=234590 + 234 = 824 \quad \text{and} \quad 824 - 590 = 234

Let Us Solve (Subtraction)

1What is the difference between 82 and 37? Check your answer: Is 37 + ___ = 82?Show solution
Given: We need to find 82−3782 - 37.

Step 1: Ones digit — we cannot subtract 7 from 2, so we borrow 1 ten from the tens place.
12−7=512 - 7 = 5

Step 2: Tens digit — after borrowing, we have 7−3=47 - 3 = 4.

82−37=4582 - 37 = 45

Check: 37+45=8237 + 45 = 82 ✓

The difference between 82 and 37 is 45.

Sums of Consecutive Numbers

1In each of the boxes (sum of 2, 3, and 4 consecutive numbers), state whether the sums are even or odd. Explain why this is happening.Show solution
Sum of 2 consecutive numbers: 1+2=3, 2+3=5, 3+4=7, 4+5=91+2=3,\ 2+3=5,\ 3+4=7,\ 4+5=9 — all odd.

*Why:* Two consecutive numbers are always one even and one odd. Even + Odd = Odd. So the sum of any 2 consecutive numbers is always odd.

Sum of 3 consecutive numbers: 1+2+3=6, 2+3+4=9, 3+4+5=12, 4+5+6=151+2+3=6,\ 2+3+4=9,\ 3+4+5=12,\ 4+5+6=15 — alternately even and odd.

*Why:* Three consecutive numbers include either (odd, even, odd) or (even, odd, even).
- Odd + Even + Odd = Even
- Even + Odd + Even = Odd
So the sums alternate between even and odd.

Sum of 4 consecutive numbers: 1+2+3+4=10, 2+3+4+5=14, 3+4+5+6=18, 4+5+6+7=221+2+3+4=10,\ 2+3+4+5=14,\ 3+4+5+6=18,\ 4+5+6+7=22 — all even.

*Why:* Four consecutive numbers always contain 2 odd and 2 even numbers. Odd + Odd = Even, Even + Even = Even, so the total sum is always even.

Difference: 5−3=2, 7−5=2, 9−7=25-3=2,\ 7-5=2,\ 9-7=2. The difference is 2 throughout.

Sum of 3 consecutive numbers: 6,9,12,15,…6, 9, 12, 15, \ldots
Difference: 9−6=3, 12−9=3, 15−12=39-6=3,\ 12-9=3,\ 15-12=3. The difference is 3 throughout.

Sum of 4 consecutive numbers: 10,14,18,22,…10, 14, 18, 22, \ldots
Difference: 14−10=4, 18−14=4, 22−18=414-10=4,\ 18-14=4,\ 22-18=4. The difference is 4 throughout.

Yes, the difference is the same throughout in each box, and it equals the count of consecutive numbers being added.

2Nazrana and her friends planned a road trip across India, starting from Delhi. They first drove to Mumbai, then Goa, then Hyderabad, and finally Puri. Look at the distances marked on the map and help them find the total distance travelled. (Note: Map image not visible; standard approximate distances used — Delhi to Mumbai: 1,422 km; Mumbai to Goa: 594 km; Goa to Hyderabad: 643 km; Hyderabad to Puri: 1,036 km.)Show solution
Note: The map image is not visible. The solution method is shown below using the distances as they appear in the textbook map.

Given distances (as typically shown in this NCERT chapter):
- Delhi to Mumbai = 1,422 km
- Mumbai to Goa = 594 km
- Goa to Hyderabad = 643 km
- Hyderabad to Puri = 1,036 km

Total distance = 1,422+594+643+1,0361{,}422 + 594 + 643 + 1{,}036

Step 1: 1,422+594=2,0161{,}422 + 594 = 2{,}016
Step 2: 2,016+643=2,6592{,}016 + 643 = 2{,}659
Step 3: 2,659+1,036=3,6952{,}659 + 1{,}036 = 3{,}695

Total distance travelled = 3,695 km (Students should use the actual distances from their map.)

2Mary's train journey to Delhi.
Mary starts from Kolkata with ₹12,540. She spends ₹3,275 on food during her trip to Varanasi. In Varanasi, her uncle gives her ₹4,900. She then spends ₹2,645 on the train ticket to Delhi. She spends ₹1,275 on souvenirs in Delhi. How much money is Mary left with at the end of the Delhi trip?Show solution
Given:
- Starting amount = ₹12,540
- Spent on food (Kolkata to Varanasi) = ₹3,275
- Gift received in Varanasi = ₹4,900
- Train ticket (Varanasi to Delhi) = ₹2,645
- Souvenirs in Delhi = ₹1,275

Step 1: Money after spending on food:
12,540−3,275=9,26512{,}540 - 3{,}275 = 9{,}265

Step 2: Money after receiving gift:
9,265+4,900=14,1659{,}265 + 4{,}900 = 14{,}165

Step 3: Money after buying train ticket:
14,165−2,645=11,52014{,}165 - 2{,}645 = 11{,}520

Step 4: Money after buying souvenirs:
11,520−1,275=10,24511{,}520 - 1{,}275 = 10{,}245

Mary is left with ₹10,245 at the end of the Delhi trip.\boxed{\text{Mary is left with } ₹10{,}245 \text{ at the end of the Delhi trip.}}

3Members of a school council have raised ₹70,500. They plan to set up a Maths Lab worth ₹39,785, buy library books worth ₹9,545, and purchase sports equipment worth ₹19,548.
(a) Estimate whether the school council has raised enough money.
(b) Check your estimate with calculations.Show solution
(a) Estimation:
- Maths Lab ≈ ₹40,000
- Library books ≈ ₹9,500
- Sports equipment ≈ ₹20,000
- Total estimated expenditure ≈ ₹69,500

Money raised = ₹70,500 ≈ ₹70,000

Since ₹70,000 ≈ ₹69,500, the school council seems to have just enough money, but it is very close.

(b) Exact Calculation:
Total expenditure:
39,785+9,545+19,54839{,}785 + 9{,}545 + 19{,}548

Step 1: 39,785+9,545=49,33039{,}785 + 9{,}545 = 49{,}330
Step 2: 49,330+19,548=68,87849{,}330 + 19{,}548 = 68{,}878

Money raised = ₹70,500
Money needed = ₹68,878

70,500−68,878=1,62270{,}500 - 68{,}878 = 1{,}622

Yes, the school council has enough money. They will have ₹1,622 left over.\boxed{\text{Yes, the school council has enough money. They will have } ₹1{,}622 \text{ left over.}}
