☆Hello my friend!!!
15/100 ×(A+B)=25/100×(A-B)
15A/100+15B/100=25A/100-25B/100
15A/100-25A/100=-25B/100-15B/100
-10A/100=-40B/100
A/10= 2B/5
A=2B/5×10
A=4B
As in question:
A=B%
A=B/100
=A/B ×100
=4B/B×100
=400%
Hence option (a)
☺☺☺

(A+B)*15/100 = (A-B)*25/100
0.15A + 0.15B = 0.25A - 0.25B
0.25A - 0.15A = 0.15B + 0.25B
0.10A = 0.40B
A = (0.40/0.10)*B
A = 4*B
to find A is what percentage of B
=(A/B)*100
=(4*B/B)*100
=400%
hope so it is right.
