Two numbers A and B are such that the sum of 8% 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.
Choices.
A) 2 : 1	B) 1 : 2	C) 4 : 3	D) 1 : 3	E) 3 : 2
Explanation:   8% of A + 4% of B = 2/3(6% of A + 8% of B)   8A/100 + 4B/100 = 2/3(6A/100+8B/100)   ⇒8A + 4B = 2/3(6A + 8B)   ⇒24A + 12B = 12A + 16B   ⇒ 12A = 4B   ⇒ AB = 4/12   ⇒ A:B=1:3   Answer: Option 1 : 3
