10.If a village is losing 10% of its water supply each day because of a burst water pipe, then what is the loss in rupees per day?
I. The daily water supply to the village is 600 million gallon.
II. The cost to the village for every 48000 gallons of water lost is Rs.50.

SOLUTION

Solution (41-50)
1. B
From statement I:
Relative speed = 3x + 4x = 7x units
Sum of Length of trains = 700 m
Required time = 700/7x = no result
From statement II:
speed of train P = x/12 = (x + 600)/25

=> 25x = 12x + 7200
=> 13x = 7200
=> x = 7200/13

2. C
Statement I:
We know that, difference between the compound interest 
and the simple interest= (PR2)/1002
320 = (32000* R2)/100*100
R= 10%
Statement II:
Let P=100
n=14
We know that, SI= pnr/100
Amount = 3P = 300
Interest = 300 – 100 = 200
If we substitute these values we can find the rate 
ofinterest per annum.
Hence Either Statement I or statement II is sufficient to 
answer the question.

3. D
Even from the both the statement we are not able to get 
the data about the number of students who can write 
French. Hence, both the statement are not sufficient to 
answer the question.

4. B
From I: 360/(b+s) + 360/(b-s) = 30
=> 240b = (b^2 – s^2)
This cannot solve alone.
From II: 360/b + 360/b = 28.8
=> b = 25 km/hr
This statement alone is sufficient.

5. C
From statement I: r = (100*100)/1000 = 10%
P = Rs. 1000 , r = 10%, t = 3 years
Hence, CI can be described.
From statement II: SI = (1000*r*2)/100 = 20r
CI = 1000[(1+(r/100)^2) – 1] Therefore, CI – SI = 
1000[(1+(r/100)^2) – 1] – 20r
=> r = 10
Hence , CI can be determined.

6. E
SP= MP*75/100 =3MP/4
From B: SP= CP*116/100 =26CP/25
29CP/25 = 17603
CP = 15175
MP= 4*(17603)/3= 23470.67
Both the statements are needed.

7. D
From Statement I:
Sum is not given. So, statement I alone is not sufficient 
to the answer the question.
From Statement II, Time period is not given. So, 
Statement II alone is not sufficient to the answer the
question.

8. B
From I. (P + Q + R) can do the work in 93/13 days.
Hence, from I alone we cannot get the answer.

From II.

(P + Q)’s one day work = 1/10 part of the work……… 
(i)
(Q + R)’s one day work = 1/20 part of the work……….. 
(ii)
(P + R)’s one day work = 1/15 part of the work………… 
(iii)
∴ 2(P + Q + R)’s one day work = 1/10 + 1/20 +1/15 = 
13/60
∴ (P + Q + R)’s one day work = 13/120………….. (iv)
By subtracting (iii) by (iv), we get Q’s one day work.
∴ Q’s one day work = 13/120 - 1/15 = 5/120 = 1/24
Hence, from II alone we can get the answer.

9. E
From I: Let the marks obtained by Sushma and Suraj in 
quarterly exam be 9x and 8x resp.
Nothing is known about their marks in half-yearly exam.
So, this statement is not sufficient alone.
From II: Let the marks obtained by Sushma in quarterly 
exam and half-yearly exam be 2y and 3y resp.
Also, let the marks obtained by Suraj in quarterly exam 
and half-yearly exam be 4z and 5z resp.
So, this is also not sufficient alone.
Combining both the equations, we get
Let the marks obtained by Sushma and Suraj in quarterly 
exam be 9x and 8x resp.
Now, 9x*(3/2) + 8x *(5/4) = 1410
=> x = 60
So, the marks obtained by Sushma in half-yearly exam = 
9x*(3/2) = 810

10. E
I –> Loss of water supply = 6000000 gallon
II–> The loss in rupees

Both statements I and II required to answer the question.
