50 increase is. 20
100. ==. ?(X)
(By cross multiplication)
X=(100×20)÷50
X=40.

We know that percentage is nothing but for 100
So. Percentage is 40%
For cross verifying
50×40%
(50×40)÷100=20
And in question thre is increase of 50 to 70. ie. 70-50 = 20. There is an increase of 20 and by our percentage method also we got 20
