Question

pens are bought at 12 for a Rupee and sold at 9 for a Rupee find gain or loss percent​

Answer 1

Step-by-step explanation:

L.C.M of 12 and 9 = 108

Let the S.P of 9 pens and C.P of 12 pens be 108 rupees

C.P of 1 pen = 108/12 = 9 rupees

S.P of 1 pen = 108/9 = 12 rupees

Gain = S.P - C.P

=12 rupees - 9 rupees

=3 rupees

------------------

Gain Percent =Gain/C.P * 100 Percent

=3 rupees / 9 rupees * 100 Percent

=100 / 3 Percent

=33.34 Percent
