Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A : B.
Choose the correct choice from the following answers:
A) 2:3  B) 3:2  C) 1:3  D) 4:3  E) 3:4
5% of A + 4% of B = 2/3 (6% of A + 8% of B)   5/100*A + 4/100*B = 2/3(6A/100 + 8B/100)   ==&gt; A/20 + B/25 = A/25 + 4B/75   ==&gt; (1/20 - 1/25)A = (4/75 - 1/25)B   ==&gt; A/100 = B/75   ==&gt; A/B = 100/75 = 4/3   Required ratio = 4 : 3   Answer 4:3) 4:3
