Question

Find a single equivalent increase if a no. is successively increased by 5% 10% and 15%

Answer 1

Hlw mate


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%.

Answer 2

Answer:

Step-by-step explanation:

For 5% and 10%

the single equivalent increase is (15+(50/100))%

=(15+0.5)%= 15.5%

Now for 15.5% and 15%

the single equivalent increase is (30.5 + (15.5*15/100))

=(30.5 +2.32)% = 32.8%

So the net single equivalent increase is 32.8%
