Question
B is thrice as efficient as A and C is 0.75 times as
efficient as A. What is the ratio of number of days taken by A, B and C when they work individually?Solution
Let the efficiency of A be 100. Given that B is thrice as efficient as A ⇒ Efficiency of B = 300 Also given that C is 0.75 times as efficient as A ⇒ Efficiency of C = 75  From the given data, We need to find the ratio of several days A, B, and C when they work individually LCM of 100, 300, and 75 is 300 Ratio of several days when they work individually. ⇒ 300/100: 300/300: 300 /75 =3:1:4
