Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1. Apple juice costs 56p for a 1-litre carton. Mango juice costs £1.20 for a 1-litre carton.

A pack of 80 plastic cups costs £1. Nita sells her fruit drink at a school concert in 250ml cups for 60p each.

We are told that Nita sells all her 80 cups

100 pence = £1

60p =

= 60/100

= £0.6

Hence, the selling price =

£0.6× 80

= £ 48

Profit = Selling Price - Cost Price

We have to find the Cost Price

A pack of 80 plastic cups costs £1.

Nita is making a fruit drink. She mixes apple juice and mango juice in the ratio 3 : 1.

3 + 1 = 4

1 liter = 1000ml

For Apple Juice

3/4 × 1000ml = 750ml

For Mango Juice

= 1/4 × 1000ml = 250ml

This means she uses a mixture of 750 ml of Apple juice and 250 ml of Mango juice

Apple juice costs 56p for a 1-litre carton.

£0.56 = 1 liter = 1000ml

1000ml = £0.56

750 ml =

= 750 × 0.56/1000

= £0.42

Mango juice costs £1.20 for a 1-litre carton.

1000ml = £1.20

250 ml = x

x = 250 × 1.20/1000

= £0.3

Hence, the total cost for 1000ml of mixed juice = £0.3 + £0.42

= £ 0.72

We are told the content of each cup = 250 ml

For 80 cups she would need

80 × 250 ml

= 20000ml of the mixed juice

If 1000 ml = £0.72

20000ml = x

x = 20000 × £ 0.72/1000

x = £14.4

1 pack of 80 cups cost £1

Hence: £14.4 + £1

Cost Price = £15.4

Profit = Selling Price - Cost Price

Profit = £48 - $15.4

Profit = £32.60

Therefore, the money she gives to the school fund is £32.60
