Views:136051
Aptitude questions form an important part of Deloitte's first round of recruitment. Quantitative aptitude is the first section of its written test. It evaluates the basic mathematical knowledge, problem-solving ability, time management, and speed-solving skills of the candidates. These questions are mainly from the topics of arithmetic, number system, geometry, probability, permutations & combinations, logarithms, etc. Here are some sample questions for Deloitte aptitude test:
###### Deloitte Aptitude Questions
1. The mean daily profit made by a shopkeeper in a month of 30 days was Rs. 350. If the mean profit for the first fifteen days was Rs. 275, then the mean profit for the last 15 days would be
1. Rs. 200
2. Rs. 350
3. Rs. 275
4. Rs. 425
Average would be : 350 = (275 + x)/2
On solving, x = 425.
1. There were 35 students in a hostel. If the number of students increases by 7, the expenses of the mess increase by Rs. 42 per day while the average expenditure per head diminishes by Re 1. Find the original expenditure of the mess.
1. Rs. 480
2. Rs. 520
3. Rs. 420
4. Rs. 460
Let d be the average daily expenditure
Original expenditure = 35 × d
New expenditure = 35 × d + 42
New average expenditure will be :
(35 × d + 42)/42 = d - 1
On solving, we get d = 12
Therefore original expenditure = 35 × 12 = 420
2. The ratio between the number of passengers travelling by I and II class between the two railway stations is 1 : 50, whereas the ratio of I and II class fares between the same stations is 3 : 1. If on a particular day Rs. 1,325 were collected from the passengers travelling between these stations, then what was the amount collected from the II class passengers?
1. Rs. 750
2. Rs. 1000
3. Rs. 850
4. Rs. 1250
Let x be the number of passengers and y be the fare taken from passengers.
3xy + 50xy = 1325 => xy = 25
Amount collected from II class passengers = 25 × 50 = Rs. 1250.
1. A boat travels upstream from B to A and downstream from A to B in 3 hours. If the speed of the boat in still water is 9 km/hour and the speed of the current is 3 km/hour, the distance between A and B is
1. 4 km
2. 8 km
3. 6 km
4. 12 km
Let d be the distance between A and B
So, d/12 + d/6 = 3 d = 12 km
2. A man while returning from his factory, travels 2/3 of the distance by bus, ¾ of the rest partly by car and partly by foot. If he travels 2 km on foot, find the distance covered by him.
1. 24 km
2. 22 km
3. 28 km
4. 26 km

Therefore D = 24 km
1. The fuel indicator in a car shows 1/5th of the fuel tank as full. When 22 more liters of fuel are poured in to the tank, the indicator rests at the 3/4of the full mark. Find the capacity of the tank.
1. 25 litres
2. 35 litres
3. 30 litres
4. 40 litres
x/5 + 22 = 3x/4 ⇒ x = 40 litres
2. A pump can be operated both for filling a tank and for emptying it. The capacity of the tank is 2400 m3. The emptying capacity of the pump is 10m3 per minute higher than its filling capacity. Consequently, the pump needs 8 minutes less to empty the tank than to fill it. Find the filling capacity of the pump.
1. 45 m3/min
2. 40 m3/min
3. 50 m3/min
4. 55 m3/min
(2400/x) - (2400/(x + 10)) = 8, Solving this we get x
= 50m3/min
Or by options (2400/50) - (2400/60) = 48 - 40 = 8 minutes
3. A sum of money is accumulating at compound interest at a certain rate of interest. It simple interest instead of compound were reckoned, the interest for the first two years would be diminished by Rs. 20 and that for the first three years, by Rs 61. Find the sum
1. Rs. 7000
2. Rs. 8000
3. Rs. 7500
4. Rs. 6500
4. In a kilometer race, A can give B a 100 m start and C a 150 m start. How many meters start can B give to C?
1. 50
2. 50/9
3. 8500/9
4. 500/9
5. None of these
