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!

Perimeter of 1st figure = 10+7+6+5+4+12 = 44 cm
In second figure two opposite sides make 7+7 = 14 cm
So, remaining two sides = 44 - 14 = 30 cm
So, one side is 30/2 = 15 cm
