Time ratio of A, B and C = 15 : 30 : 75
As we know,
Efficiency ratio is inversely proportion to time.
Efficiency ratio of A, B and C = 1/15 : 1/30 : 1/75 or 150/15 : 150/30 : 150/75 or 10 : 5 : 2
Efficiency ratio of A, B and C = 10x : 5x : 2x
According to the question
10x + 5x + 2x = 1615
⇒ 17x = 1615
⇒ x = 1615/17
⇒ x = 95
The difference between share A and C = 10x – 2x = 8x = 8 × 95 = 760
