Answer 1

Answer:

Rose bought green mangoes at P50.00 a kilo and sold them at 4 for P35.00.

If she sold 20 kilos and there is an average of 7 mangoes per kilo,

how much did she earn?

:

Find the cost she paid for each Mango: 50%2F7

Find the no. of mangoes sold: 20 * 7 = 140 mangoes

Find the price she sold each Mango: 35%2F4

:

Let p = profit she made by buying and selling these Mangos

:

p = 140(%2835%2F4%29+-+%2850%2F7%29)

p = 140(%28245%2F28%29+-+%28200%2F28%29)

p = 140(45%2F28)

p = 5(45)

p = 225 P profit on 20 kilos of Mangoes

Hope it will help you..

Answer 2

Find the cost Rose paid for each green mango=Rs 50/7

Find the number of mangoes  sold = 20×7 = 140

Find the price she sold each mango = 35/4

Let 's consider p = profit she made by buying and selling mangoes

= 140 {  ( 35/4)  -  ( 50/7)}

= 140 { ( 35×7 - 50×4)÷28 }

 =140 { ( 245/28 ) - ( 200/28) }

 =140 ( 45/ 28)

 =5× 45

= 225 P

∴ Profit on 20 kg mangoes is 225 P.

Ans :- Rose gained 225 P.
