Question

Decrease 150 km/hr by 20%.
pls its urgent

Answer 1

Step-by-step explanation:

A simple rule of three will do.

150 km/h is to 120% as x is to 100%.

x = 150/(120/100)=125 km/h

Answer 2

120km/hr.

First of all , find the 20% of 150.

So, 20% of 150 = (20/100) × 150.

= 150/5.

= 30.

So, 150km/hr- 30km/hr.

= 120km/hr.
