Answer 2

70

EXPLANATION

We want to increase 50 by 40%

Method 1

New amount =50+40% of 50

`= 50 + (40)/(100) * 50`

`= 50 + (40)/(2)`

`= 50 + 20`

`= 70`

Method 2.

50 corresponds to 100%.

New amount corresponds to (100+40=140)%

This implies that, New amount

`= 140\% * 50`

`= (140)/(100) * 50`

`= (140)/(2)`

`= 70`
