Question

An article is sold at 40% gain an the cost price. Find the ratio of the selling price and cost price.

Answer 1

An article is sold at 40% gain

100 + 40 = 140

If the cost price is 100 then the selling price 100 + expenditure is 4x – 1000 + 40 = 140 

∴ \(\frac{SP}{CP} = \frac{140}{100} \)

= \(\frac{7}{5}\)

∴ SP : CP = 7 : 5
