17. A Fruity Number...
Two mangoes and four bananas cost £1.82
Scroll down the page for the answer.
So if a = number of apples, b = number of bananas and m = number of mangoes, then
2m + 4b = 182
add both these equations to get
4a + 4b + 4m = 336
4(a + b + m) = 336
a + b + m = 84
so the cost is £0.84
