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.

Its not working in all conditions.
Try this,
When a No. Divided by 32 it gives reminder the 21, what will be the reminder when the No. is divided by 18?

(39-17) = 22.
(22-17) = 5 answer.
(22-17) = 5 answer.

Apply the formula for this:
When a number is divided by 32 it leaves reminder of 21. What will be the remainder when the number is divided by 18?

39
357*39 = y.
13923 = y.
x - y = 39.
x - 13923 = 39.
x = 13962.
Divide 13962 by 17 you will get 5 as remainder.

Divide 13962 by 17 you will get 5 as remainder.

357 * k + 39 = x.
(357 * k + 34) + 5 = x.
17 (21k + 2) + 5 = x.
Then the remainder is 5.
(357 * k + 34) + 5 = x.
17 (21k + 2) + 5 = x.
Then the remainder is 5.

If I change the question like:
A number when divided by 17 leaves remainder 5 then what remainder would be obtained by dividing the same number by 357?
Can anyone answer me?
