Annie bought a mobile and sold it to Ben at a profit of 50%. After few days, Ben sold it back to Annie at 40% loss, and then Annie sold it to Charlie at 30% profit. Find the overall profit percentage of Annie?

A. 40.53%

B. 77%

C. 87%

D. 90%

E. 95%

An easy way to solve such problems is by assuming numbers.

Since Annie sold the mobile and sold it to be Ben for a 50% profit.

If the cost price of the mobile is $100, she would have sold it for $150.

Profit = $50Now Ben sold it back to Annie for a 40% loss, at 0.6*150 = $90

Now, that Annie sold it again to Charlie for 30% profit - 1.3*90 = $117.

Profit = $27Therefore, the overall profit percentage for Annie is \(\frac{$50+$27}{$100} = \frac{77}{100}\) =

77%(Option B)
