Question

Items A and B cost price equal, item A sold at 40% profit and item B sold at 20%less than the selling price of item A, total profit is 189.find the cost price of A?
a)440
b)420
c)480
d)485

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

The cost price is thus 363.46
