 A

8.

 B

 C

9.

 D

10.

Soln.
Ans: a

Since the work force is being doubled proportionately, the time is halved = 8 days.


Question 2

A and B can complete a job in 16 and 64 days. They start together but A leaves after working for 6 days. How long would B take to finish the job counting from the day both A and B started together?

 A

40 days.

 B

41 days.

 C

39 days.

 D

43 days.

Soln.
Ans: a

If B takes x days. The total job is A's work in 4 days + B's work in x days = $6/16$ + $x/64$ = 1. Solving, we get x = 40 days.


Question 3

A can do a work in 3 days. B can destroy the work in 14 days. In how many days will they together complete the work?

 A

$3{9/11}$ days.

 B

$4{9/11}$ days.

 C

$5{9/11}$ days.

 D

$6{9/11}$ days.

Soln.
Ans: a

Putting x = 3 and y = 14 in the shortcut method, we get ${xy}/{y - x}$ = ${42/11}$, which is same as: $3{9/11}$.


Question 4

A can harvest a field in 12 days. B can do the same work in 18 days. C can do the same work in 5 days. In how many days will they together harvest the field?

 B

$3{58/61}$ days.

 C

$4{58/61}$ days.

 D

$5{58/61}$ days.

Soln.
Ans: a

Putting x = 12, y = 18 and z = 5 in the shortcut method, we get ${xyz}/{xy + zy + zx}$ = ${180/61}$, which is same as: $2{58/61}$.


Question 5

6 men and 4 women finish a job in 30 days. In how many days will 8 women and 12 men finish that job?
