### Question 1

Mr. X can finish a task in 15 days. Mr. Y can do the same work in 17 days. What is the ratio of the efficiencies of X : Y?

### Question 2

A, B and C complete a work in 16, 10 and 18 days respectively. All three of them start the work together, but A leaves the work after 1 days. In how many days will the work be completed?

**A**

$6{3/112}$ days.

**B**

$7{3/112}$ days.

**C**

$8{3/112}$ days.

**D**

$9{3/112}$ days.

**Soln.**

**Ans: a**

Use the shortcut formula. If A, B, C can independently complete the job in x, y and z days, and A leaves after n days, the work is completed in ${yz}/{y + z}$ × $(1 - n/x)$ days. Putting the various values x = 16, y = 10, z = 18, n = 1, and simplifying, we get ${675/112}$, which is same as: $6{3/112}$.
