On dividing a number by 357, we get 39 as remainder. On dividing the same number 17, what will be the remainder ?
Answer: Option
Explanation:
Let x be the number and y be the quotient. Then,
x = 357 x y + 39
= (17 x 21 x y) + (17 x 2) + 5
= 17 x (21y + 2) + 5)
Required remainder = 5.

357)x(y
39 then
357*y+39=x
21*17*y+17*2+5=x
17(21y+2)+5=x
Then 5 is remainder.
39 then
357*y+39=x
21*17*y+17*2+5=x
17(21y+2)+5=x
Then 5 is remainder.

You can simply divide 39 by 17, then you will get the answer, i.e., remainder 5. :-).
