Question 1

Mr. X can finish a task in 13 days. Mr. Y can do the same work in 8 days. What is the ratio of the efficiencies of X : Y?

 A

${8/13}$.

 B

$1{8/13}$.

 C

${2/3}$.

 D

${9/14}$.

Soln.
Ans: a

The efficiency of X is $100/13$%, and the efficiency of Y is $100/8$%, so the ratio will be $8/13$


Question 2

6 men and 4 women finish a job in 10 days. In how many days will 8 women and 12 men finish that job?

 A

5.

 B

4.

 C

6.

 D

7.

Soln.
Ans: a

Since the work force is being doubled proportionately, the time is halved = 5 days.


Question 3

A can harvest a field in 15 days. B can do the same work in 8 days. C can do the same work in 17 days. How much did A get if the farmer pays them a total amount of Rs. 12000 for a work that they together completed in 5 days?

 A

Rs. 4000.

 B

Rs. 4100.

 C

Rs. 3900.

 D

Rs. 4300.

Soln.
Ans: a

Work done by A in 1 day = $1/15$. So the work in 5 days = 5 × $1/15$. His share is Rs. 5 × $1/15$ × 12000 = Rs. 4000.


Question 4

A can harvest a field in 5 days. B can do the same work in 14 days. C can do the same work in 3 days. In how many days will they together harvest the field?

 A

$1{83/127}$ days.

 B

$2{83/127}$ days.

 C

$3{83/127}$ days.

 D

$4{83/127}$ days.

Soln.
Ans: a

Putting x = 5, y = 14 and z = 3 in the shortcut method, we get ${xyz}/{xy + zy + zx}$ = ${210/127}$, which is same as: $1{83/127}$.


Question 5

Mr. P is thrice as efficient as Mr. Q and can finish a piece of work by taking 22 days less. In how many days does Mr. P finish that work?

 A

11.

 B

10.

 C

12.

 D

13.

Soln.
Ans: a

Let the time taken by P be x days. Then the time taken by Q is 3x. The difference is 3x - x. So, 2x = 22. Solving, x = 11.
