On dividing a number by 357, we get 39 as remainder. On dividing the same number 17, what will be the remainder ?
Options:
A . 0
B . 3
C . 5
D . 11
E . None of these
Answer: Option C Let x be the number and y be the quotient. Then, x = 357 × y + 39 = (17 × 21 × y) + (17 × 2) + 5 = 17 × (21y + 2) + 5 ∴ Required remainder = 5
