The product of two numbers is 9375 and the quotient, when the larger one is divided by the smaller, is 15. The sum of the number is:
(A) 395
(B) 380
(C) 400
(D) 425

A number divided by 68 gives the quotient 269 and remainder zero. If the same number is divided by 67, the remainder is:
(A) 2
(B) 3
(C) 0
(D) 1
Number = 269 × 68
= 269 × (67 + 1)
= 269 × 67 + 269
Clearly, remainder is obtained on dividing 269 by 67 that is 1.
