All fruits together = 100% OR x Apples = 30% of x OR 30/100 of x = 3/10 x Oranges= 50% of (x - 3/10 x) OR 1/2 of (x - 3/10 x) = 1/2 of 7/10 x = 7/20 x Pears = 20/20(All Fruits) - {6/20(Apples) + 7/20(Oranges)} = 20/20 - 13/20 = 7/20 Therefore it is clear that 7/20 of all fruits is pears. Hope this was helpful!
