You can set-up the equation as n=25k+13, k is a constant.mlane25269 wrote:Can someone explain? Thanks!
Statement I
n<100
25(1)+13 = 38
25(2)+13 = 63
25(3)+13 = 88
Not Sufficient.
Statement II
n = 20k+3
if we compare this equation with the equation in the question stem
n = 20(3)+3 = 63
n = 25(2)+13 =63
but we also have to consider the other possibilities as well.
n=20(8)+3 = 163
n=25(6)+13 = 163
Therefore, Not sufficient.
Statement I & II
n=25k+13 & n<100 & n=20k+3
Only answer that satisfies all the above conditions is 63.
Hence C.
