When the integer n is divided by 2, the quotient is u and the remainder is 1. When the
integer n is divided by 5, the quotient is v and the remainder is 3. Which one of the following
must be true?
(A) 2u + 5v = 4
(B) 2u – 5v = 2
(C) 4u + 5v = 2
(D) 4u – 5v = 2
(E) 3u – 5v = 2
Any number N, in terms of it's Divisor, Quotient and Remainder can be written as;
N = (Divisor)(Quotient) + RemainderNow,
N = 2u + 1 ....... (1)
N = 5v + 3 ....... (2)
Equating 1 and 2;
2u + 1 = 5v + 3
2u - 5v = 2
Hence, option B
