**Answers With Explantion :**

1.D)

Raju can do 1/15 of the job per day

John can do 1/20 of the job per day

If they work together they can do 7/60 of
the work together

**Remaining job 1 - 4*7/60 = 32/60 = 8/15**

2.C)

Ram can type 32/6 pages per hour

Shaam can type 8 pages per hourThey can
type 32/6 + 8 = 40/3 pages per hour

So they will take

**110/40 × 3 = 33/4 hours or 8 hours 15 minutes**
3.E)

7 men can do 1/12 of the job per day

So after 5 days they have completed 5/12th
job. Still 7/12 part of the job is to be completed.

5 men can do 1/12 × 5/7 = 5/84 of the job
per day

So they will take 7/12 × 84 /5 =

**9****⅘****days to complete the job**
4.B)

Efficiency of A = 1/20 = 5% per day

Efficiency of B = 1/30 = 3.33% per day

Efficiency of C = 1/60 = 1.66% per day

In three days A can do 15% of the job himself
and B and C do 5% of the job ( 1.66% + 3.33% )

In three days they can do 20% of the job,
to do 100% of the job,

**they need 3 × 5 = 15 days**
5.B)

As per question, A do twice the work as
done by B.

So A:B = 2:1

Also (A+B) one day work = 1/18

To get days in which B will finish the
work, lets calculate work done by B in 1 day =

=(1/18∗1/3)=1/54

[Please note we multiplied by 1/3 as per
B share and total of ratio is 1/3]

**So B will finish the work in 54 days**

6. Let the number of questions attempted by
Mohan with correct answers be x. Then, total marks obtained for correct answers
= x * 1 = x And the number of questions attempted by Mohan with incorrect
answers = 30 – x. Total marks deducted for incorrect answers = (30 – x)/4 Now, x – (30-x)/4 = 13.75

Or, 4x + x = 13.75 + 30 = 55
+ 30 = 85 or, 5x = 85 , x = 85/5 = 17

**Incorrect answers = 30 – 17 = 13**

7.
Let the monthly income be Rs. X

Then,
(x * 13)/100 = 305500 x = (305500 *
100)/13 = Rs. 2350000

Now, total monthly amount invested by
Mr. Sharma = 29 + 9 + 13 = 51%

So,

**51% of 2350000= (51*2350000)/100 = Rs. 1198500**
8.
Here in the given word GALOTIA, there are seven letters, where A appears twice.
Hence the rqd number of ways

**= 7!/2! = 3 * 4 * 5 * 6 * 7 = 2520****9. Can't determined.**

**10. Rs. 2052.26**

11.A) Total increase = 8 * 2 = 16 years So, total
age of two women = 35 + 45 +16= 96

**Average age of two women=96/2=48 years**

12.C)
2, 4, 6, ………… 100

**Average = (1st No. + Last No.) /2 = (2+100)/2 = 51**

13. A) S.I. for 3 years = Rs. (12005 - 9800) = Rs.
2205.

S.I. for 5 years= Rs. 3675

Principal = Rs. (9800 -
3675) = Rs. 6125

**Hence Rate = {(100 × 3675) / 6125 × 5} % = 12 %**

14. A) Let C.P. be Rs. x and S.P. be Rs. y.

Then, 3(y - x) = (2y - x) y = 2x. Profit = Rs. (y - x) = Rs. (2x -
x) = Rs. x.

**So profit % =100%**
15. D)

Short tricks : Let the
initial investment money ratio of Jon and Harry is 2x and 3x So Jon , Harry and
Ron ratio of investment is ( Jon : Harry : Ron )

**= (2x X 12 ) : ( 3x X 12 ) : ( 3x X 6 ) = 24 : 36 : 18 = 4 : 6 : 3**

16.
B) :

Suppose Ramesh invested Rs. x. Then,

Manoj : Ramesh = 120000 * 6 : x *12.

720000/12x: 6000/3000

**x = 30000**

17. C) Let speed of cyclist = x kmph
480/(72 - x) X 5/18 = 32

**x = 18 kmph**
18. A) Let speed of 1st train = x kmph (180 + 120)/(x X 5/18) = 20

**x = 54 kmph**

19.Let the number to be added x , Then 3 +
x / 5 + x = 5 / 6 6 ( 3 + x ) = 5 ( 5
+ x ) x = ( 25 – 18 ) = 7

**So , the number to be added is 7 .**

20. Profit= 5% (If case ) 5% of CP ------> Rs. 27 So, CP = Rs. 540

Now, Loss% = 10

Loss =Rs. 54

**Required % = 54*100/27 = 200%.**
