Answer 2

Answer:

Answer:

80

Step-by-step explanation:

Given akbar sells a chair at a gain of 7.5% if he bought it at 12.5% less and sold it for 5 more, he would have gained 30% the cost price of chair

Let cost price be x, so gain is 7.5%

Selling price = 107.5 x / 100

If he had bought it at 12.5% less and sold it for Rs 5 more, cost price = 87.5 x/100

So selling price = 107.5 x/100 + 5

Gain = (107.5 x /100 + 5) – 87.5 x/100 = 20 x/100 + 5

Now gain = 30%

So 20 x/100 + 5 = 87.5 x/100 x 30/100

X = 5000 / 62.5

X = 80

So cost price of chair is Rs 80
