4,79,032

Step 1: Total attendance = Monday attendance + Tuesday attendance. Step 2: 1,26,844 + 3,52,188 Step 3: Add column by column: 4+8=12 (write 2 carry 1), 4+8+1=13 (write 3 carry 1), 8+1+1=10 (write 0 carry 1), 6+2+1=9, 2+5=7, 1+3=4. Step 4: Total = 4,79,032. Verify: The answer should be between 4 lakh and 5 lakh since we are adding about 1.27 lakh and 3.52 lakh.

What is the sum of the largest 4-digit number and the smallest 5-digit number?

Show answer

19,999

Step 1: Find the largest 4-digit number = 9,999. Step 2: Find the smallest 5-digit number = 10,000. Step 3: Add them: 9,999 + 10,000 = 19,999. Step 4: Check - 9,999 + 10,000: add ones 9+0=9, tens 9+0=9, hundreds 9+0=9, thousands 9+0=9, ten-thousands 0+1=1. Answer = 19,999. Common mistake: Some students think the largest 4-digit number is 10,000 - remember it's 9,999!

Which number should be added to 4,85,319 to get 7,00,000?

Show answer

2,14,681

Step 1: We need to find: 4,85,319 + ? = 7,00,000. Step 2: This means ? = 7,00,000 - 4,85,319. Step 3: 7,00,000 - 4,85,319 = 2,14,681. Step 4: Verify by adding: 4,85,319 + 2,14,681: 9+1=10 (carry 1), 1+8+1=10 (carry 1), 3+6+1=10 (carry 1), 5+4+1=10 (carry 1), 8+1+1=10 (carry 1), 4+2+1=7. Answer = 7,00,000. Correct!
