Two numbers 4242 and 2903 when divided by a certain number of three digits, leave the same remainder. Find the number?
Correct answer: B. 103
- A. 101
- B. 103
- C. 107
- D. 113
Explanation
If two numbers leave the same remainder, their difference must be exactly divisible by the required divisor. Their difference is 4242 - 2903 = 1339, and 1339 ÷ 103 = 13, so 103 is suitable. The likely mistake is option a, 101, which does not divide 1339 exactly.
