If 40% of a number is equal to two-third of another number, what is the ratio of first number to the second number?  Choose the correct choice from the following choices
A) 5:3
B) 3:5
C) 1:5
D) 5:1
E) None of them
Let 40% of A = 2/3 B   Then, 40A/100= 2B/3   = 2A/5 = 2B/3   = A/B = (2/3) x (5/2)= 5/3   Therefore, A : B = 5 : 3.   5:3nswer is 5:3.
