Answer 1

Answer:

Correct option is

A

2%

Let the CP bex

MP=120%×x=1.2x

Gain while selling half stocks of goods=0.5(1.2x−x)=0.1x

Gain while selling remaining one quarter stocks of goods=0.25[(20%×1.2x)−x]=−0.01x

Gain while selling remaining stocks of goods=0.25[(40%×1.2x)−x]=−0.07x

Net gain=(0.1−0.01−0.07)x=0.02x

Gain%=

CP

gain

×100

⟹

x

0.02x

×100=2%
