A man bought two shirts for Rs. 650. He sold one of them at a gain of 7% and the other at a loss of 6%. On the whole he neither gained nor lost ? The cost of the shirts, respectively, were

300, 350

We have,

The combined price of two shirts = Rs.650 

Gain on one shirt = 7%

Loss on another shirt = 6%

Gain on one shirt = loss on another shirt 

⇒ 7% of CP₁ = 6% of CP₂

⇒ CP₁/CP₂ = 6/7

⇒ CP₁ = (6/13)× 650 = 300

⇒ CP₂ = (7/13)× 650 = 350
