Question

Rose bought green mangoes at P50 a kilo and sold them at 4 for P35. If she sold 20 kilos and there is an average of 7 mangoes per kilo, about how much did she gain?

Answer 1

P = 225 P profit on 20 kilos of mangoes

Values:

Mangoes sold:
`20*7=140\\`

Cost paid for each mango:
`(50)/(7)`

Price each melon sold for:
`(35)/(4)`

Explanation:

1. Substitute given values;
`P = 140((35)/(4) - (50)/(7))`

2. Find common denominator:
`P=140((245)/(28)-(200)/(28) )`

3. Subtract equation in parentheses:
`P=140((45)/(28) )\\`

4. Divide
`140\\` by
`28` to remove denominator;
`P=5(45)`

5. Solve equation:
`P=225`
