(b) 66.66%

(d) 37.75%

(e) 33.33%

S8. Ans.(b)

Sol.

Let the correct weight be 1 kg and C.P. be Rs 1/g

Quantity purchased by the shopkeeper = 1250 g

Quantity sold by the shopkeeper = 750 g

We have

S.P. of 750 g = C.P. of 1250 g

⇒ S.P. of 750 g = Rs 1250

⇒ C.P. of 750 g = Rs 750

Therefore, profit by selling 750 g of item =1250-750=Rs 500

Profit percentage =500/750×100

= 66.66%
