Paper 2 Question 1

Four friends buy three different kinds of fruit in the market. When they get home they cannot remember the individual prices per kilogram, but three of them can remember the total amount that they each paid.

The weights of fruit and the total amounts paid are shown in the following table.

Suresh Fandi Cindy Lee Lian
Pineapples (kg) 1.15 1.20 2.15 1.30
Mangoes (kg) 0.60 0.45 0.90 0.25
Lychees (kg) 0.55 0.30 0.65 0.50
Total amount paid in $ 8.28 6.84 13.05

Assuming that, for each variety of fruit, the price per kilogram paid by each of the friends is the same, calculate the total amount that Lee Lian paid.
