Question

Mohan bought 10 dozens of pens at Rs 30 each. If 20 pens were stolen and sold the remaining pens for Rs. 40 each find his profit or loss?​

Answer 1

First we should find C.P of the pens

10 dozens of pens =12×10=120 pens

₹30 each

=120×30=₹3600

So, C.P=₹3600

now we should find S.P

given 20 pens were stolen and he sold each pen for ₹40

total pens=120-10=100

S.P=100×40=₹4000

Profit=S.P-C.P(if S.P>C.P)

=4000-3600

=₹400 of profit

So, the total profit is ₹400
