Question 75

A table was sold at a profit of 10%. If its cost price was 5% less and it was sold for Rs. 7 more, the gain would have been 20%. Find the cost price of the table.

Solution

Let the cost price be Rs x.

Then selling price = Rs. 1.1x

A/c to question, If its cost price was 5% less and it was sold for Rs. 7 more, the gain would have been 20% ,

then new CP = .95x

new SP = 1.1x + 7

$$\frac{1.1x + 7 - .95x}{.95x} \times 100 = 20$$

x = 175

So, the answer would be option a)Rs. 175
