5 pears + 5 mangoes
8 pears + 4 mangoes
They cost the same.
Find the difference by removing the number of fruits in common.
8 pears - 5 pears = 3 pears
5 mangoes - 4 mangoes = 1 mango
So 3 pears cost the same as 1 mango.
Mango = 3 units
Pear = 1 unit
Difference = 2 units = $3.70
Cost of 1 pear = 1 unit = $3.70 ÷ 2 = $1.85
Cost of 1 mango = $1.85 x 3 = $5.55
