Answer 2

Answer:

Given, for first transistor

S.P = Rs. 840

Profit =20 %

Now, with this S.P. and for Profit % =

C.P.

S.P.−C.P.

×100=20 %

⇒

C.P.

840−C.P.

×100=20

⇒840−C.P.=0.20C.P.

⇒1.20C.P.=840

⇒ C.P. = Rs. 700

And for another transistor

C.P= Rs. 700+ Rs. 25= Rs. 725

Profit =20 %

So, Profit % =

C.P.

S.P. −C.P.

×100=20

=

725

S.P. −725.

×100=20

⇒ S.P.−725=145

⇒ S.P.= Rs. 870
