A is twice as fast as B and B is one third as fast as C. If they together can complete work in 30 days. In how many days, A, B and C individually can do the same work?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 1 - Question 16 Condition 1- A is twice as fast as

B, means their ratio is 2: 1.

Condition 2- B is one third as fast

as C, means their ratio is 1: 3. Then we can say, the ration of A, B and C is as follows

According to condition 1,

A : B = 2 : 1

According to condition 2;

B : C = 1 : 3

Thus, Ratio of A : B : C = 2 : 1 : 3

This ratio denotes the working efficiency of A, B and C which means;

A, B and C can do = (2 + 1 + 3 = 6) work/day

Now we can calculate total work i.e.

Total work = Total days × Per day work

Total work = 30 × 6 = 180

A can do the same work in;

= (Total work / Efficiency of A) = 180 / 2 = 90 days

B can do the same work in;

= (Total work / Efficiency of B)

180 / 1 = 180 days

C can do the same work in;

= (Total work / Efficiency of C) = 180 / 3 = 60 days

Thus, A, B and C can individually complete the same work in 90, 180 and 60 days, respectively.
