Answer 1

Hey Friends,
______________________________

S.P. for Sohan =Rs. 14,400
Loss%=10%
C.P. =[100/(100 - Loss%)]x S.P.
C.P. =[100/(100 - 10 )]×14,400
C.P. =100/90×14,400
C.P. =Rs. 16,000

C.P. for Rahul = 16,000
Profit%=7%
S.P. =[(100 + Gain %)/100]x C.P.
S.P. =[(100 + 7)/100]×16,000
S.P. =107/100×16,000
S.P. =Rs. 17,120

S.P. for Rahul =Rs. 17,120


Hope it's help you!!!!

Answer 2

Answer:

S.P. for Sohan =Rs. 14,400

Loss%=10%

C.P. =[100/(100 - Loss%)]x S.P.

C.P. =[100/(100 - 10 )]×14,400

C.P. =100/90×14,400

C.P. =Rs. 16,000

C.P. for Rahul = 16,000

Profit%=7%

S.P. =[(100 + Gain %)/100]x C.P.

S.P. =[(100 + 7)/100]×16,000

S.P. =107/100×16,000

S.P. =Rs. 17,120

S.P. for Rahul =Rs. 17,120
