Question

Two items A and B are sold at a profit of 10% and 15% respectively. If the amount of profit received is the same, then the cost price A and B may be

Answer 1

here , 10 % of cost price of A = 15 % of cost price of B

10 / 100 × cost price of A = 15/100 × cost price of B

10 × cost price of A = 15 × cost price of B

cost price of A / cost price of B = 15/10

cost price of A / cost price of B = 3/2

cost price of A : cost price of B = 3 : 2

The prices of A and B are in the ratio 3 : 2
