Question

A number is increased by 25 and the decreased by 20 percent. Find the change in that number

Answer 1

Answer:

lets take the number as x

when increased by 25% ,

=x + 25x/100

= x + x/4

= 5x / 4

Now we have to decrease 20% of the new number formed ie 5x / 4

=5x/4 - 20/100 × 5x/4

= 5x/4 - 5x/20

= (25x - 5x) / 4

= 20x / 4

= 5x

Hence the number formed in the end is 5x

Change in the number is given as ,

5x - x = 4x

The change in the number is 4x

Hope it helps:)
