Answer:

25 chairs

Step-by-step explanation:

If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?

The percent gain = 60%

Number of chairs to be sold = x

Hence:

40 chairs = 10,000

60/100= 40 - x/x × 100

0.6= 40 - x/x

Cross Multiply

0.6x = 40 - x

0.6x + x = 40

1.6x = 40

x = 40/1.6

x = 25 chairs
