: 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 Mangos
