Two numbers are respectively 20% and 50% more than a third number. What is the ratio of the two numbers?
A
2:5
B
3:5
C
4:5
D
6:5
Correct Option:
C

If the third number is 100, the other two are 120 and 150. Their ratio is 120:150=4:5. Using 100 as the base turns percentage language into ordinary arithmetic.
