Question: On dividing a number by 56, we get 29 as remainder. On dividing the same number by 8, what will be the remainder ?
[A].4
5
6
7
[A].
[B].
[C].
[D].
Answer: Option B
Explanation:
Formula: (Divisor*Quotient) + Remainder = Dividend.
Soln:
(56*Q)+29 = D ——-(1)
D%8 = R ————-(2)
From equation(2),
((56*Q)+29)%8 = R.
=> Assume Q = 1.
=> (56+29)%8 = R.
=> 85%8 = R
=> 5 = R.
