Question

If a discount of 10℅ be given on the M.P of a shirt, the seller gains 20℅ . if the discount is increase to 15℅, what will be the gain percent?​

Answer 1

Answer:

Step-by-step explanation:

Let Selling price be SP and cost price be CP

So (100%–10%) SP = CP (100%+20%)

Or 0.9 SP = 1.2 CP

SP = 1.2/0.9 CP = 1.33 CP

If discount is increased to 15%

SP (100% - 15%) = CP ( 100% + x%)

0.85 SP = CP ( 100% + x%)

0.85 * 1.33 CP = CP (100% + x%)

x = 13.33%
