On selling an item for Rs 276 a person gains 15%. In order to gain 35%, What should be the increase in its selling price ?
A). Rs. 48
B). Rs. 50
C). Rs. 56
D). Rs. 61
Rs. 48
Let the cost of item be x.
∴ x + x x 15/100 = 276
or, x = 27600/115 = 240
For 35% gain, selling price
= 240 + 240 x 35/100 = 240 + 84 = 324
∴ Required increase in price = 324 - 276 = 48
