A man bought 2 shirts, which together cost him ₹ 480. He sold one of them at a loss of 15% and the other at a gain of 19%. If the selling price of both the shirts are equal, find the cost price of the lower priced shirt.
₹ 200
Let the cost price of one shirt be ₹ x and other be ₹ (480 - x).
Loss = 15%
SP = CP - Loss
SP = x−15x100
∴ SP = 85x100 ............(i)
Gain = 19%
SP = CP + Profit
SP = (480−x)+19×(480−x)100
∴ SP = 119(480−x)100................(ii)
Since the SP of both shirts are equal, we can equate (i) and (ii).
85x100 = 119(480−x)100
⇒ 85x=119×480 −119x
⇒ 204x=119×480
⇒ x=119×480204
⇒ x=280
∴ Lower priced shirt
= 480 - 280
= ₹ 200
