Question

A man sells a sofa for 3120 making a profit of 7%. what would have been if he had sold it for 3360​

Answer 1

Answer:

33.6%

Step-by-step explanation:

3120×7÷100=218.4

3120-218=2901.6 (.6 is negligible)

3360-290=458

458÷3360×100=ans

Answer 2

Step-by-step explanation:

SP of sofa = 3120 rupees.

Profit when selling the sofa = 7percent.

$cp = \frac{100 \times sp}{100 + profit}$

$cp = \frac{100 \times 3120}{100 + 7}$

$cp = \frac{312000}{107}$

CP = 2915.88 rupees.

In second case; sp is 3360.

so, SP - CP

=》3360 - 2915.88

=》 444.12 rupees

$100 \times \frac{444.12}{2915.88}$

by solving that we get, 15.23 percent.
