Question

The income of A is 50% more than that of B. If the income of A is increased by 40% and the income of B is increased by 90% , then the percentage increase in their combined income will be.

Answer 1

Answer:

Step-by-step explanation:

Let the income of b be 100x therefore income of a which is 50% greater than that of b is (100+50%*100)=150

Initial combined income of a and b 100 +150=250

Now income of a is increased by 40

40%*150+150=60+150=210

Increase in b income =(90%100+100=90+100=190)

New combined income of a and b =(210+190=400)

Increase =[(new-old) /old ]*100

(400-250)/250*100

=60% change(answer)
