Solutions:
1. C) Sum of ages of George and Martin is 64 years.
Let George’s present age be T years
Martins present age = (64 T) years
Five years back, George’s age was half of Martin’s age
T 5 = 1/2 × (64 T 5) 2 × (T 5) = 64 T 5 2T - 10 = 59 – T 3T = 69 T = 23
Martins present age = 64 - T = 41
Martins present age is 41 years 
2. C) The ratio of three angles of a right angled triangle is 13 : 2 : 15.
Let the angles be 13T, 2T and 15T.
Largest angle of a right angled triangle = 90°
15T = 90 T = 6
Measure of angle that is neither smallest nor largest = 13T = 13 × 6 = 78°
3. C) Out of 15 member team, 11 are to be selected in playing team.
Since captain will definitely be a part of playing team, our task reduces to selecting 10 players out of 14.
This can be done in 14C10 ways.
We know, nCr  nCn-r 
 14C10 14C14-10 14C4
Playing team can be selected in 14Cways, i.e. (14 × 13 × 12 × 11)/(4 × 3 × 2 × 1) = 1001.
4. C) Let the length of the train be x m and the speed be y m/s.
While crossing a man, train covers a distance equal to its own length.
x/y = 5
x = 5y
While crossing a platform, train covers a distance equal too its own length and length of platform.
length of train and platform together = (x + 154) m
(x + 154)/y = 12
x + 154 = 12y
5y + 154 = 12y    (Putting the value x = 5y)
y = 154/7 = 22
Length of the train = 5 × 22 = 110 m
Speed of the train = 22 m/s
5. C) We know, Average of quantities =sum of all quantities/no. of quantities
The average temperature on Sunday, Monday and Tuesday was 45 °C. Then total temperature of Sunday, Monday and Tuesday = 45° ×3 = 135°C
The average temperature on Monday and Tuesday and Wednesday it was 40 °C. Then total temperature of Monday and Tuesday and Wednesday = 42° ×3 = 126°C
As on Wednesday it was exactly 40 °C.Then total temperature of Monday and Tuesday = (126° – 40°)C = 86°C
The temperature of Sunday = total temperature of Sunday, Monday and Tuesday - total temperature of Monday and Tuesday = (135° - 86°)C = 49 °C
6. C) Price of resultant mixture = [Price of 20 lt milk + Price of 7 lt water]/(20 + 7)
Price of 4 liters of resultant mixture = 4 × [Price of 20 lt milk + Price of 7 lt water]/(20 + 7)
= 4 × [(20 × 54 + 7 × 0)/27] = 160
Price of 4 liters of resultant mixture is Rs. 160.
7. A) When they move in opposite direction,
Their relative speed = (9 + 6) km/hr = 15 km/hr
Time taken = 9 minutes = 9/60 hours
Distance covered = speed × time
Distance covered = (15 × 9/60) km
Distance covered = 9/4 = (9/4) × 1000 = 2250 m
8. B) We know that,
For 2 years, difference between S.I. and C.I. = P (R/100)^2
Where, P = principal and R = rate of interest
 Required difference = (7300 × 36)/10, 000 = Rs 26.28
Hence, the required difference between simple and compound interest is Rs 26.28
9. B) Ratio of shares of A, B and C = Ratio of their investments for 2 years
= [(5000 × 2): (7000 × 2): (6000 × 2)] = [10000: 14000: 12000] = 5: 7: 6
Given: Net profit earned = Rs. 10,800
Bs share = Rs.7/18 × 10800 = Rs.4200
10. C) Let the faulty pipe can empty the tank in x hrs, then
Net part filled in 1 hr = 1/20 + 1/24 – 1/x = 1/15
1/x = 1/20 + 1/24 – 1/15 = (6 + 5 – 8)/120 = 3/120 = 1/40
By comparing both sides, we get x = 40.
The faulty pipe can empty the tank in 40 minutes.
Since rate of leakage = 3 gallons per minute
Volume of tank/rate of leakage = time taken by faulty pipe to empty the tank
Volume of the tank/3 = 40
Volume of the tank = 40 × 3 = 120 gallons
11. C) Average mileage of cars R and S = (12 + 13)/2 = 12.5
Percentage by which mileage of car P is greater than average mileage of cars R and S = [(18 – 12.5)/12.5] × 100 = 44
12. D) The manufacturers of car S have decided to increase its engine capacity by 10% every year and decrease mileage by 10% every year.
After 1 year, mileage of car S = 13 – 13 × (10/100) = 11.7
Since, the mileage will degrease further in coming years, it will always be less than that of car R.
After 1 year, engine capacity of car S = 1500 + 1500 × (10/100) = 1650
After 2 years, engine capacity of car S = 1650 + 1650 × (10/100) = 1815
After 3 years, engine capacity of car S = 1815 + 1815 × (10/100) = 1996.5
After 4 years, engine capacity of car S = 1996.5 + 1996.5 × (10/100) = 2196.5 > 2000
From end of first year to end of fourth year, mileage and engine capacity of car S will be less than that of car R, that is for a total of 3 years.
13. B) Average mileage of all cars = (18 + 16 + 12 + 13)/4 = 59/4 = 14.75
Average engine capacity of all cars = (1200 + 1000 + 2000 + 1500)/4 = 5700/4 = 1425
Longevity = Mileage/Engine capacity = 14.75/1425 = 0.01035
14. D) Suppose ground clearance of car Q is increased by T mm.
(144 + T) is 15% more than 153
144 + T = 153 + 153 × (15/100) = 175.95
T = 31.95
Ground clearance of car Q should be increased by 31.95 mm.
15. B) Ratio of mileage to engine capacity for car P = 18/1200 = 0.015
Ratio of mileage to engine capacity for car Q = 16/1000 = 0.016
Ratio of mileage to engine capacity for car R = 12/2000 = 0.006
Ratio of mileage to engine capacity for car S = 13/1500 = 0.0087
Clearly, the ratio is highest for car Q.
