Solution:

Q2. Two pipes A and B can fill a tank in 20 hours and 25 hours respectively and a third pipe C can empty the tank in 50 hours. All of three pipes opened together and after sometimes pipe C is closed. If total time to fill the tank from beginning is 13 hours, find after how much time pipe C was closed?

11 hrs
9 hrs
8.5 hrs
7.5 hrs
10.5 hrs.
Solution:

Q3. There are 6 filling pipes each capable of filling a cistern alone in 16 minutes and 4 emptying pipes each capable of emptying a cistern alone in 20 minutes. All pipes are opened together and as a result, tank fills 28 litres of water per minute. Find the capacity of the tank.

145 l
160 l
240 l
180 l
154 l
Solution:

Q4. A pipe can fill a cistern in 12 min and another pipe can fill it in 15 min but a third pipe can empty it in 6 minutes. The first two pipes are kept open for 5 minutes in the beginning and then the third pipe is also opened. Time taken to empty the cistern is:

Q5. Taps A, B and C are attached with a tank and velocity of water coming through them are 42 litre per hours, 56 litre per hours and 48 litre per hours, respectively. A and B are inlets and C is outlet. If all the taps are opened simultaneously, tank is filled in 16 hours. What is the capacity of the tank?

2346 litres
1600 litres
800 litres
960 litres
2330 litres
Solution:

Capacity of tank = 42×16+56×16-48×16
= 800 liters

Solution:

Directions (11-15): pie chart given below shows the percentage distribution of females in five cities and table shows the total number of literates (male + female) in these five cities. 

Total population of any city = Male + Female
Total males = Literate + Illiterate
Total female = Literate + Illiterate

Q11. If ratio of total literate female to total illiterate female in city A is 5 : 3 and total literate males in city A are 75% of total females of city A, find no of literate males in city A.

30000
25000
20000
45000
35000
Solution:

Q12. If ratio of literate male to literate female in city C and E are 45 : 41 and 45 : 38 respectively then what is the ratio of literate female of city C to literate female of city E.

53 : 17
43 : 17
41 : 19
40 : 19
50 : 21
Solution:

Let literate male and literate female in city C be 45x and 41x
And literate male and literate female in city E be 45y and 38y
So,
45x + 41x = 172000
x = 2000
and, 45y + 38y = 83000
y = 1000
Required ratio = 41x/38y
= 82000/38000
= 41 : 19

Q13. If in city B total literate females aremore than literate males and ratio of literate male to illiterate male is 11 : 3 then total males in city B are what percent of total literate female of city B.

Solution:

Q14. Total male and female in city D is 145000 if total illiterate female in city D are equal to total literate female in city D then find the difference in number of literate males and illiterate male in city D

55000
53000
57000
60000
50000
Solution:

Total male and female in city D = 145000
Total illiterate male and female in city D = 145000 – 99000
= 46000
Literate male + Literate female = 99000
Illiterate male + Illiterate female = 46000
But illiterate females are equal to literate female in city D
Let total illiterate female in city D = total literate female in city D = x
So,
Literate male + x = 99000 …(i)
Illiterate male + x = 46000 …(ii)
Subtracting (ii) from (i)
Literate male – Illiterate male = 53000

Q15. If total females in all six cities is 400000 and in city E total female literate areof total literate males then what is the ratio of literate male in city E to total illiterate females in city E.

15 : 4
12 : 5
