Question

Two items A and B have equal cost price. Item A is sold at 40% profit and item B is sold at an amount 20% less than the selling price of item A. If the total profit is 156 Rs then find the cost price of A.
A. Rs. 300
B. Rs. 350
C. Rs. 400
D. Rs. 450
E. None of these

Answer 1

Let the cost price =C

The cost price for A and B are equal.

The selling price of A=(140 /100)×C =1.4C

The selling price of B is 20% less of A then it means the selling price is 80% of the selling price of A.

Solving this we get:(80/100) × 1.4C =1.12C

The profit for A is:0.40C and the profit for B is 0.12C

The total profit is 0.40C+0.12C

0.52C

This equals to 189.

0.52C =189

C=363.46

Answer 2

the answer is C= 400 (363.46)rupees
