Important Questions from A2 Mathematical Modelling
Juhi has ₹600 and the bicycle costs ₹1800 cash. The bank loan rate is 10% per annum simple interest, while the instalment scheme works out to about 13.14%. Which option is more economical for Juhi?
Show answer
Bank loan
The bank charges 10% simple interest, which is lower than the instalment scheme rate of about 13.14%. The lower rate makes the bank loan more economical.
In the fish population estimate, 20 fishes were marked and released. A second sample of 50 had 5 marked fishes. What is the estimated total population?
Show answer
200
In the second sample, 5 out of 50 were marked, so the marked fraction is 1/10. If 1/10 of the population is 20, then the whole population is 20 × 10 = 200.
A sample of 20 fishes is marked in a lake. Later, 50 fishes are caught and 5 are found marked. What fraction of the second sample is marked, and what reciprocal is used to estimate the population?
Show answer
1/10 and 10
The marked part of the second sample is 5/50 = 1/10. The reciprocal of 1/10 is 10, and that factor is used to estimate the whole population.
A pair of dice is rolled. Which sum has the greatest probability according to the probability table for sums from 2 to 12?
Show answer
7
The probability table shows that sum 7 has probability 6/36, which is higher than any other sum. Therefore, 7 is the most likely sum.
