Question

If 15% of (a+b) equals to 25% of (a-b) then what will be the % of b equals to a ?

Answer 1

Answer:

(a+b)15/100=(a-b)25/100

3(a+b)=5(a-b)

3a+3b=5a-5b

5b+3b=5a-3a

8a=2b

Therefore,

a=(b)1/4

Let 'X' percent of b equal to a.

(b)(X/100)=a

Since a=(b)1/4

bx/100=b(1/4)

x/100=4

Therefore

x=400
