B is equal to A?
(a) 10%
(b) 60%
(c) 100%
(d) 200%
(e) 400%​

Answer 1

Answer:

400% of b=a

Step-by-step explanation:

Given

15%of(a+b) = 25%of (a-b)

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

multiply both side by 100

we get,

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

divide both sides by 5

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

3a+3b=5a-5b

3b+5b=5a-3a

8b=2a

2a=8b

a=4b

a=400%of a
