A cloth merchant professes to sell his material at a loss of 8%. But he measures 84 cm for a metre. Find his actual gain or loss per cent.

A) \[9\frac{5}{11}\]% gain             

B) \[9\frac{11}{21}\]% gain

C) % loss                   

D) % loss

Correct Answer: B

Solution :

Let CP of 1 m cloth = Rs. 100

SP of 84 cm cloth = 92

CP of 84 cm cloth = 84

\[\text{Gain=SP}-\text{CP}=92-84=8\]

Gain % x%
