## Correct Answers

- Let Kasim,Yasir and Zakir take 2x,3x & 6x days to finish the job alone. therefore in one day they will complete 1/2x,1/3x & 1/6x respectively.

Number of days taken by Kasim & Yasir together to finish the job=

1/(1/2x+1/3x)=6x/5

Number of days taken by Yasir & Zakir together to finish the job=

1/(1/3x+1/6x)=6x/3

Required ratio=3:5

**Option (C)**

- Kabir takes 20 days to complete the work.

Vikrant is 80% as efficient as kabir.Therefore, he can do the same work in 25 Days.

Working together,they can complete the work in

=1/20+1/25

=9/100

=100/9days

**Option (A)**

- Arun does 5% work per day and shreya does 4% work per day.

Together they do 9% work per day.

In seven days, Shreya does 28% work.

Hence Arun and Shreya must have completed 72% work when they worked together.This implies that Arun left after working for 8Days.

If Shreya had left the work after 8 days, Arun would have taken 28/5 days to complete the work.

Required ratio= 28/(5*7)=4/5

**Option (D)**

- In 3 days, Arjun does 25% of the work.

In 8 days, Preet completes 25% of the work.

Thus remaining 50% work is completed by kuldeep

Kuldeep is paid Rs.15000 for doing 50% of the work,

Arjun does 25% of the work. Thus he would be paid Rs.7500

**Option (A)**

- Man-days required to complete a job= m*d*e, where m= number of men, d=days and e= efficiency.

Hence for Job A, man-days required= x*13*E+y*13*4E=1001E

Thus 13x*E+52y*E=1001E

For Job B, man-days required= x*2E*16+y*5E*16=1792E. Thus 32x+80y=1792.

Solving for x and y, we have x=21 and y=14.

Now 4x+3=4*21+3=87 and y+9=14+9=23.Total man-days required to complete jobs A and B together=1001E+1792E=2793E man-days.

2793E=87*d*E+23*d*2E

Thus d= 2793/133=21days.

**Option (A)**

- In this question we can go through options,

Let us consider option (a)

Efficiency of Salman= 5%

Efficiency of Aamir= 4%

So, after 7 days Salman did 5*7=35% work.

Aamir did= 5*4=20% work.

So, Total work completed after 7days=55%

Work left=45% which is 9/20.

So, the first condition is satisfied.

Now, they would take 45/(4+5)=5 more days to complete thw remaining work.

So, Salman does= 35+5*5=60% of the work.

And Aamir does 40% of the work.

So, it is satisfied.

** Option (A)**

- Raman can finish 1/10part of the assignment in one day.

Sharad’s Efficiency is double so he can complete 1/5 of the assignment per day.

Together Raman and Sharad can do 1/10+1/5=3/10 of the assignment per day.

So, work left will be= (1-3/10)=7/10^{th} portion of the assignment.

**Option (C)**

- Let us use efficiency method for solving

Efficiency of Anshu=10%( Since he completes in 10 days so taking 100units of work his efficiency is 10%)

Efficiency of Shivangi=2%

Efficiency of Chetna= 4%

So, total efficiency of Anshu,Shivangi and Chetna is 16%.

Since they work for 2 days in the beginning so total work done is

32%.

For the last 3 days Chetna works alone so total work done=3*4=12%

Hence work left=(100-44)=56%

This 56% work is done by Shivangi and Chetna.

So, 56/(2+4)=28/3days.

Hence total number of days taken to complete is 2+3+28/3=43/3 days.

**Option (D)**

- Part of work done by Ram=5/10=1/2

Part of work done by shyam=1/3

Work done by sita= (1-1/2+1/3)=1/6

Ratio=1/2 : 1/3 : 1/6= 3:2:1

Ram’s Share= 3*1500/6=750

Shyam’s Share= 2*1500/6=500

Sita’s Share=1*1500/6=250

Ram’s Daily Share= 750/5=150

Shyam’s Daily Share= 50/5=100

Sita’s Daily Share= 250/2=125.

So total share of shyam and Sita is=225.

** Option (A)**

- Let us use efficiency method to solve

Let 10 units of work needs to be completed.

So,

Efficiency of kohli=10%

Efficiency of Dhoni= 5%

Efficiency of Yuvraj= 4%

So, kohli+Dhoni=15%, Dhoni+Yuvraj=9% and Kohli+Yuvraj=14%.

To reduce the number of days we have to select the pair with more

Efficiency. So, if we select Kohli+Dhoni and Kohli+Yuvraj alternately

We will get our value,

So, 15+14+15+14+15+14=87% work is done in 6 days.

So, The remaining 13% can be done in 13/15 days.

So, minimum number of days required is 6+13/15=103/15days.
