Question

a dealer gain 7% by selling a sofa set for rs 3852. find his gain per cent if he sells it for rs 4050

Answer 1

Hii..
Here is your answer..

Solution:-
Let the CP be x.
Gain=7℅
SP= x +7℅ of x
$= > x + \frac{7}{100} x = 3852 \\ = > \frac{100x + 7x}{100} = 3852 \\ = > \frac{107x}{100} = 3852$
$= > x = \frac{3852 \times 100}{107} \\ = > x = 3600$
Now,
Cost price =3600
Selling price=4050
Since,SP>CP
So,It's gain.

Gain=Sp-Cp
$= > 4050 - 3600 \\ = > 450$
$gain\% = \frac{gain}{cp} \times 100 \\ = > \frac{450}{3600} \times 100 \\ = > 12.5$
Hence,
Gain=12.5℅

Hope it helps uh...✌️✌️✌️
