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.	Options
A) 2 : 1	B) 1 : 2	C) 1 : 1	D) 4 : 3	E) None of these
Explanation :   5% of A + 4% of B = (2/3)(6% of A + 8% of B)   (5A/100) + (4B/100) = (2/3)((6A/100) + (8B/100))   ⇒ 5A + 4B = (2/3)(6A + 8B)   ⇒ 15A + 12B = 12A + 16B   ⇒ 3A = 4B   ⇒ A/B = 4/3   ⇒ A:B = 4:3   Answer : Option 4 : 3
