150 is not a multiple of 4..
ans D

As chetan2u , mentioned above,

S = 1.25 C (S=sale price, C=cost price)

---> S = (5/4)*C = (1+1/4)*C = C+ C/4

Thus for S to be an integer ---> C must be a multiple of 4. Out of the given options, only option D is NOT a multiple of 4.

D is thus the correct answer.

Hope this helps.

sales price is 5x/4, where x is the cost price. since we are working with integers only, we need to identify a number that is not divisible by 4.
D is the answer.
