(A) 5 (B) 8 (C) 10 (D) 13 (E) 25 Store X = $$80 + 20n$$ Store Y = $$180 + 17n$$ Now, $$\frac{125}{100}$$ => $$\frac{5}{4}$$ So, $$180 + 17n$$ = $$\frac{5(80 + 20n)}{4}$$ Or, $$720 + 68n = 400 + 100n$$ Or, $$32n = 320$$ So, $$n = 10$$ , Answer must be (C) _________________ Thanks and Regards Abhishek....
