1. In a retail outlet, the average revenue was Rs.10,000 per day over a 30 day period. During this period, the average revenue on
weekends (total 8 days) was Rs. 20,000 per day. What was the average daily revenue on weekdays?
A    6364
B    5250
C    6570
D    8060
A n s w e r : A
Explanation:
Total revenue of the 30-day period = Rs.10000 x 30 days = Rs.300000
Total revenue of the weekends (8 days) = Rs.20000 x 8 days = Rs. 160000
Total revenue of weekdays = (300000-160000) = Rs. 140000
Avg. daily revenue on weekdays = 140000/22 = Rs.6363.63  Rs.6364

2. Two different prime numbers X and Y, both are greater than 2, then which of the following must be true?
A    X - Y = 23
B    X + Y is not equal to 87
C    Both 1 and 2
D    None of the above.
A n s w e r : B
Explanation:
2 is the only even prime number. Rest are odd. If both X and Y are greater than 2, they must be odd and sum of 2 odd nos. can never be
odd. So option '2' is correct.
3. It takes 6 hours for pump A, used alone, to fill a tank of water. Pump B alone takes 8 hours to fill the same tank. A, B and another
pump C all together fill the tank in 2 hours. How long would pump C take, used alone, to fill the tank?
A    4.8
B    6
C    5.6
D    3
A n s w e r : A
Explanation:
Assuming tank volume to be 48 litres,
Flow rate through pump A = 48/6 = 8 litres/hr
Flow rate through pump B = 48/8 = 6 litres/hr

A    4.8
B    6
C    5.6
D    3
A n s w e r : A
Explanation:
Assuming tank volume to be 48 litres,
Flow rate through pump A = 48/6 = 8 litres/hr
Flow rate through pump B = 48/8 = 6 litres/hr
˜

.
Flow rate through pumps A, B, C together = 48/2 = 24 litres/hr
So, flow rate of pump C alone = 24 - (8+6) = 10 litres/hr
Time taken by C alone to fill the tank = 48/10 = 4.8 hrs
4. A swimming pool can be filled by pipe A in 3 hours and by pipe B in 6 hours, each pump working on its own. At 9 am, pump A is
started. At what time will the swimming pool be filled if pump B is started at 10 am?
A    11:20 a.m.
B    11:05 a.m.
C    11:10 a.m.
D    10:50 a.m.
A n s w e r : A
Explanation:
Let pool volume be 30 litres.
Flow rate through A = 30/3 = 10 litres/hr
Flow rate through B = 30/6 = 5 litres/hr
A is opened at 9:00am and then B is opened at 10:00 am. So, A alone fills the tank for an hour to 10 litres.
After 10:00am both are opened simultaneously.
Remaining 20 litres of the pool are filled at a combined flow rate of 15 litres/hr which takes 80 min to get filled.
The pool is filled 80 mins after 10:00am i.e. 11:20am

5. The sum of prime numbers that are greater than 60, but less than 70 is :
A    128
B    191

A n s w e r : A
Explanation:
There are 2 prime nos. between 60 and 70 which are 61 and 67. Their sum is 128.

8. Stuart, Jack and Leo are colleagues working in a plant. Stuart and Jack can do a work in 10 days, Jack and Leo can do the same
work in 15 days while Stuart and Leo can do it in 12 days. All of them started the work together. After two days, Leo was shifted
to some other work. How many days will Stuart and Jack take to finish the rest of the work?
A    9
B    12
C    8
D    7.5
A n s w e r : D
Explanation:
Let the total work be 120 units.
Let efficiencies of Stuart = s , Jack = j , Leo = l.
We know, Efficiency x Time = Work done.
Forming 3 eqns.:
s + j = 120 units/ 10 days = 12 units/day
j + l = 120 units/ 15 days = 8 units/day
s + l = 120 units/ 10 days = 10 units/day
On solving the above 3 eqns. , we get
s = 7 units/day , l = 3 units/day , j = 5 units/day
All 3 start together but Leo leaves after 2 days.
(15 x 2) + (12 x n) = 120
=> n = 7.5 days
To finish rest of the work, Stuart and Jack take 7.5 days.

A    9
B    12
C    8
D    7.5
A n s w e r : D
Explanation:
Let the total work be 120 units.
Let efficiencies of Stuart = s , Jack = j , Leo = l.
We know, Efficiency x Time = Work done.
Forming 3 eqns.:
s + j = 120 units/ 10 days = 12 units/day
j + l = 120 units/ 15 days = 8 units/day
s + l = 120 units/ 10 days = 10 units/day
On solving the above 3 eqns. , we get
s = 7 units/day , l = 3 units/day , j = 5 units/day
All 3 start together but Leo leaves after 2 days.
(15 x 2) + (12 x n) = 120
=> n = 7.5 days
To finish rest of the work, Stuart and Jack take 7.5 days.

such machines produce in 30 minutes?
A    225
B    300
C    250
D    350
A n s w e r : A
Explanation:
Machines are identical. So, each machine produces 180/6 = 30 bottles/hr
15 such machines will produce 450 bottles in an hour.
So, in 30 mins 15 machines will produce 225 bottles.

A    6364
B    5250
C    6570
D    8060
A n s w e r : A
Explanation:
Total revenue of the 30-day period = Rs.10000 x 30 days = Rs.300000
Total revenue of the weekends (8 days) = Rs.20000 x 8 days = Rs. 160000
Total revenue of weekdays = (300000-160000) = Rs. 140000
Avg. daily revenue on weekdays = 140000/22 = Rs.6363.63  Rs.6364

2. Two different prime numbers X and Y, both are greater than 2, then which of the following must be true?
A    X - Y = 23
B    X + Y is not equal to 87
C    Both 1 and 2
D    None of the above.
A n s w e r : B
Explanation:
2 is the only even prime number. Rest are odd. If both X and Y are greater than 2, they must be odd and sum of 2 odd nos. can never be
odd. So option '2' is correct.
3. It takes 6 hours for pump A, used alone, to fill a tank of water. Pump B alone takes 8 hours to fill the same tank. A, B and another
pump C all together fill the tank in 2 hours. How long would pump C take, used alone, to fill the tank?
A    4.8
B    6
C    5.6

A n s w e r : A
Explanation:
Assuming tank volume to be 48 litres,
Flow rate through pump A = 48/6 = 8 litres/hr
Flow rate through pump B = 48/8 = 6 litres/hr
˜

.
Flow rate through pumps A, B, C together = 48/2 = 24 litres/hr

Time taken by C alone to fill the tank = 48/10 = 4.8 hrs
4. A swimming pool can be filled by pipe A in 3 hours and by pipe B in 6 hours, each pump working on its own. At 9 am, pump A is

B    11:05 a.m.
C    11:10 a.m.
D    10:50 a.m.
A n s w e r : A
Explanation:
Let pool volume be 30 litres.
Flow rate through A = 30/3 = 10 litres/hr
Flow rate through B = 30/6 = 5 litres/hr
A is opened at 9:00am and then B is opened at 10:00 am. So, A alone fills the tank for an hour to 10 litres.
After 10:00am both are opened simultaneously.
Remaining 20 litres of the pool are filled at a combined flow rate of 15 litres/hr which takes 80 min to get filled.

A    9
B    12
C    8
D    7.5
A n s w e r : D
Explanation:
Let the total work be 120 units.
Let efficiencies of Stuart = s , Jack = j , Leo = l.
We know, Efficiency x Time = Work done.
Forming 3 eqns.:
s + j = 120 units/ 10 days = 12 units/day
j + l = 120 units/ 15 days = 8 units/day
s + l = 120 units/ 10 days = 10 units/day
On solving the above 3 eqns. , we get
s = 7 units/day , l = 3 units/day , j = 5 units/day
All 3 start together but Leo leaves after 2 days.
(15 x 2) + (12 x n) = 120
=> n = 7.5 days
To finish rest of the work, Stuart and Jack take 7.5 days.

1.25 N - 0.7 N = 22
=> N = 22/0.55 = 40

11. Running at the same constant rate, 6 identical machines can produce a total of 180 bottles per hour. How many bottles could 15
such machines produce in 30 minutes?
A    225
B    300
C    250
D    350
A n s w e r : A
Explanation:
Machines are identical. So, each machine produces 180/6 = 30 bottles/hr
15 such machines will produce 450 bottles in an hour.
So, in 30 mins 15 machines will produce 225 bottles.
12. A number whose fifth part increased by 4 is equal to its fourth part diminished by 10, is :

.
B
260
C    270
D    280
A n s w e r : D
Explanation:

13. Which of the following numbers will completely divide (461 + 462 + 463 + 464)?
A    3
B    10
C    11
D    13
A n s w e r : B
Explanation:
On adding the units digits of the numbers, we get sum as 10.
The summation will be divisible by 10.

14. Is 'b' positive?
(I) a + b is positive.
(II) a - b is positive.
A    Statement I alone is sufficient to answer the question.
B    Statement II alone is sufficient to answer the question.
C    Both statements I and II together are necessary to answer the question.
D    Both statements I and II together are not sufficient to answer the question.
A n s w e r : D
Explanation:
Case 1 - b -> positive
Let a=10, b=1.
Here (a-b) and (a+b) both are positive.
Case 2 - b -> negetive
Let a=10, b= -1.
Here also (a-b) and (a+b) both are positive.
Both statements I and II together are not sufficient to answer the question.
