Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 12 : 11.
Given:
Two numbers are, respectively, 20% and 10% more than a third number
Calculations:
Relation between the first and third number
⇒ 1st : 3rd = 120 : 100 = 6 : 5 ----- (1)
Relation between second and third number
⇒ 2nd : 3rd = 110 : 100 = 11 : 10 ---- (2)
Now, balancing the value of the third number in both equations we get
Required ratio = 12 : 11
