Question

Jai Narayan sells two radio sets for 2288
On one he gains 10% and on the other he loses
10%. Find his gain or loss per cent ?​

Answer 1

Answer:

First radio set

CP : ₹2288

Gain : 10%

SP = CP × [100 + Gain% / 100]

SP = 2288 × [100 + 10% / 100]

SP = 2288 × [110 / 100]

SP = 2288 × 11/10

SP = 1144 × 11/5

SP = 12584/5

SP = ₹2516.8

Second radio set

CP = ₹2288

Lose = 10%

SP = CP × [100 - Lose% / 100]

SP = 2288 × [100 - 10% / 100]

SP = 2288 × [90/100]

SP = 2288 × 9/10

SP = 1144 × 9/5

SP = 10296/5

SP = ₹2059.2

Total CP = ₹2288 + ₹2288 = ₹4576

Total SP = ₹2516.8 + ₹2059.2 = ₹4576

Since, CP = SP

Hence, No Gain and No Lose

Hope it helps
