Q:

Raghu can complete a work in 12days working 9 hours a day. Arun can complete the same work in 8 days working 11 hours a day. If both Raghu and Arun work together, working 12 hours a day, in how many days can they complete the work ?

A) $\inline \fn_jvn \small 3\tfrac{4}{49} days$    B) $\inline \fn_jvn \small 12\tfrac{4}{49} days$  C)  $\inline \fn_jvn \small 4\tfrac{3}{49} days$   D)  $\inline \fn_jvn \small 4\tfrac{12}{49} days$

 A) Option A B) Option B C) Option C D) Option D

Explanation:

Raghu can complete the work in (12$\fn_jvn&space;\small&space;\times$9)hrs = 108 hrs.
Arun can complete the work in (8$\fn_jvn&space;\small&space;\times$11)hrs = 88 hrs.
Raghu's 1 hrs work = $\inline \fn_jvn \small \frac{1}{108}$ and Arun's 1 hrs work = $\inline \fn_jvn \small \frac{1}{88}$
(Raghu + Arun)'s 1 hrs work = $\inline \fn_jvn \small \left ( \frac{1}{108}+\frac{1}{88} \right ) = \frac{49}{2376}$
So, both Raghu and Arun will finish the work in $\inline \fn_jvn \small \left ( \frac{2376}{49}\right ) hrs$
Number of days of 12 hours each=$\inline \fn_jvn \small \left ( \frac{2376}{49}\times \frac{1}{12} \right )$ = $\inline \fn_jvn \small \frac{198}{49} = (4\tfrac{3}{49}) days$.

Q:

K can finish the work in 18 days and L can do the same work in 15 days. L worked for 10 days and left the job. In how many days, K alone can finish the remaining work ?

 A) 5.5 days B) 6 days C) 4.2 days D) 5 days

Explanation:

L's 10 days work = $\inline \fn_jvn \small \left ( \frac{1}{15}\times 10 \right )= \frac{2}{3}$
Remaining work = $\inline \fn_jvn \small \left ( 1-\frac{2}{3} \right )=\frac{1}{3}$
Now, $\inline \fn_jvn \small \frac{1}{18}$ work is done by K in one day
$\inline \fn_jvn \small \frac{1}{3}$ work is done by K in $\inline \fn_jvn \small \left ( 18\times \frac{1}{3} \right ) = 6 days$

Q:

Twenty men can do a work in eighteen days. Eighteen women can complete the same work in fifteen days. What is the ratio between the capacity of a woman and a man ?

 A) 4:5 B) 3:4 C) 4:3 D) 2:3

(20$\fn_jvn&space;\small&space;\times$18) men can complete the work in in one day.
one man's one day work = $\inline \fn_jvn \small \frac{1}{360}$
(18$\fn_jvn&space;\small&space;\times$15) women can complete the work in 1 day
1 woman's one day work = $\inline \fn_jvn \small \frac{1}{270}$
So, required ratio = $\inline \fn_jvn \small \frac{1}{270} :\frac{1}{360}$ = 4:3
