Answer:
100
Step-by-step explanation:
Step-by-step :Let b 's income is x % more of a
Given,
a=b-50.%ofb-(i)
Sol,
B=a+x%of a
Now,putting value of a from eqn i
B=B-50B/100+X%(B-50B/100)
B =(100B-50B)/100 +Bx/100-
50Bx/10000
B =50B/100+(100Bx-50Bx)/1000
B =50B/100+50Bx/10000
B=B(1/2 +x/200)
B/B=1/2+x/200
x/200=B/B-1/2
x/200=1-1/2
X/200=1/2
X=200/2
So,x=100
By,x% ,B is greater to A.
