Question

A grocer sells rice at a profit of 10% and used weights which are 20% less than the market weight. The total gain earned by him will be

• A. 30%
• B. 35%
• C. 37.5%
• D. None of these

Answer 1

The correct option is C 37.5%

let us consider a packet of rice marked 1 kg

Its actual weight is 80% of 1000 gm = 800 gm

Let C.P. of each gm be Rs. 1

then, C.P. of this packet = Rs. 800

S.P. of this packet = 110% of C.P. of 1 kg

$=(\frac{110}{100}\times 1000)=Rs.1100$

$\therefore Gain=(\frac{300}{800}\times 1000)\%$

$=37.5\%$
