Question

Find a single equivalent increase, is a number is
successively increased by 20%, 25% and 30%
(1) 90% (2) 75% (3) 95%
(4) 85% (5) None of these

Answer 1

Answer:

Let the number be 100 then after the first increase of 20% the new number is 120.

then after the second increase in the no. of 25% the new no. is 120*25/ +120

=120*1/4=30+120

therefore the new no. is 150

the after the third increase of 30%

the new no.is 150*30/+150

=45+150

=195

Now the first no. was 100.

new no.is 195

therefore the successive increase is (195-100)%

=95%.
