If 4M = 5N = 20C, then what is the value of M : N : C ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 5 : 4 : 1.
4M = 5N = 20C
Taking the first two ratios
4M = 5N
⇒ M : N = 5 : 4.....(1)
Now, taking the last two ratios
⇒ 5N = 20C
⇒ N : C = 20 : 5
⇒ N : C = 4 : 1.....(2)
So, Froim eq 1 and 2
⇒ M : N : C = 5 : 4 : 1
