Bananas and mango

5 kg of bananas and three kilograms of mango cost 146 CZK, two kilograms of bananas and 5 kilograms of mango cost 142 CZK. How much is a kilogram of bananas, and how many mangoes?

Correct result:

b =  18.6316
m =  20.9474

Solution:


5b+3m=156
2b+5m=142

5•b+3•m=156
2•b+5•m=142

5b+3m = 156
2b+5m = 142

b = 354/19 ≈ 18.631579
m = 398/19 ≈ 20.947368
