- If 40% of a number is equal to two-third of another number, what is the ratio of first number to the second number?
Question 1:
If 40% of a number is equal to two-third of another number, what is the ratio of first number to the second number?
A. 5:3
Feedback Let the Two numbers be A, B
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
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
B. 7:3
C. 3:7
D. 4:7
