Question

Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is?

Answer 1

Let the 3rd nos be 100.

⇒Then, 1st nos = 120% of 100= 120*100/100= 120

⇒2nd nos = 150% of 100 = 150*100/100 = 150

Ratio of 1st :2nd =  120: 150=   4 : 5. ANS

Answer 2

Let the third number is X No 1 X+(20X/100) No 2 X+(50X/100)   No 1/No 2 (6X/5)/(3X/2) =12/15
