Question

Rahul sold a watch to Sohan at a gain of 10% and Sohan sold it to Mohan at a loss of 10%.If Mohan paid ₹990 for it, find the price paid by Rahul.​

Answer 1

Hey mate ♡♡

Step-by-step explanation:

Let the C.P of the watch when Rahul bought it be x rs.

gain % when sold to Sohan=10% of x

gain made=rs.10/100×x=x/10

S.P for rahul=gain +C.P

=x+x/10

=11x/10

S.P for rahul= C.P for sohan=11x/10

loss % when sold to Mohan=10% of 11x/10

loss=11x/100

S.P for sohan=C.P- loss

=11x/10-11x/100

=99x/100

S.P for sohan=C.P for Mohan

A/Q

990=99x/100

=)990×100÷99=x

=)x = 1000
