Answer 2

Answer:

The fruitseller paid Rs. 433.59 for all the apples.

Step-by-step explanation:

Given that:

Profit = 20%

No. of apples = 12 * 3

                       = 36

Selling Price (SP) = Rs. 12 per apple.

Let the Cost Price (CP) of 1 apple be Rs. 'x'

Therefore, profit = 20 * CP / 100

                           = x/5

We know that Profit = SP - CP

                           x/5 = 12 * 36 - x * 36

                           $\frac{x}{5}$ = 436 - 36x

=>                         x = 5 (436 - 36x)

=>                          x = 2180 - 180x

=>              x + 180x = 2180

=>                    181 x = 2180

=>                          x = 12.044

Therefore the CP of all apples = 12.044 * 36

                                                   = 433.59

Therefore, the fruitseller paid Rs. 433.59 for all the apples.
