Question

A number is increased by 15% and then decreased by 25%. Find the net increase or decrease
​

Answer 1

Answer:

160

Step-by-step explanation:

Let the number is = 100x

Now after 15% of increase = 100x + 15% of 100x = 115x

Now 25% decrease = 115x - 25% of 115x = 115x - 28.75x = 86.25x

Actual decreased = 100x - 86.25x = 13.75x

According to the question,

13.75x = 22

x = 2213.75

100x = 2213.75

× 100 = 160

∴ Original number = 160
