A - A shopkeeper sold an article at 20% profit. Had he sold the article for Rs. 20 less and he reduces the cost price of article by Rs.40, then he gains 5% more profit. What is the cost price of the article?

B - The cost price of article which he sold for Rs. 960 at 25% profit.

A = 25% of B, B =  33⅓ % of C, B = 25% of D, A =  6 ¼ % of D, C = 75% of D and A = 40% of E.

The values of A, B, C, D and E are integer values and all the values are less than 50.

x - What is the sum of values of (A + B + C + D + E)?

y - 123
