Answer»

GIVEN,

Let COST price of A be Rs. M

Profit PERCENTAGE = 20%

⇒ 20 = [(S.P - M)/M] × 100

⇒ M = 5 S.P - 5 M

6 M = 5 S.P

⇒ S.P = 6 M/5

Cost price of a B = 6 M/5

Profit percentage = 25%

⇒ 25 = [(225 - 6 M/5)/(6 M/5)] × 100

⇒ 6 M/5 = 900 - 24 M/5

⇒ 6 M = 900

⇒ M = 150

∴ Cost price of A is Rs. 150.
