A : B = 12 : 17 and A is 20% more than C. If B is 15% less than D, then C is what percentage of D?
Answer & explanation
Correct answer: option 2
Given :-
A : B = 12 : 17
Now , A is 20% more than C . i.e
A : C = 6 : 5 OR 12 : 10
B is 15% less than D . i.e.
B : D = 85 : 100
B : D = 17 : 20
So , Ratio of A , B , C & D
A : B : C : D
12 : 17 : 10 : 20
Required percentage = \(\frac{10}{20}\) × 100 = 50%
