Question

Manoj purchased a video for ₹12000. He sold it to Rahul at a of 10% . If Rahul sells it to Rakesh at a loss of 5% , what did Rakesh pay for it?

Answer 1

For Manoj,
CP=₹12000
Gain=10%
SP=₹[(100+gain%)×CP/ 100]
=₹[(100+10)×12000/100]
=₹[110×12000/100]
=₹13200
Again,
For Rahul
CP=₹13200
loss=5%
SP=₹[(100-loss%)×CP/100]
=₹[(100-5)×13200/100]
=₹[95×13200/100]
=₹12540
Hence, Rakesh pay for ₹12540
