  • 1. If a boat goes 7 km upstream in 42 minuters and the speed of the stream is 3 kmph, then the speed of the boat in still water is
A.) 11 km/hr
B.) 12 km/hr
C.) 13 km/hr
D.) 14 km/hr

Answer: Option 'C'

Speed Upstream = 7/42 km/min = 7/42 × 60 km/hr
i.e, b = 10 km/hr
speed of the stream = 3 km/hr
Let speed in sttil water is x km/hr
Then, speed upstreeam = (x - 3) km/hr
x - 3 = 10 or x = 13 km/hr

  • 2. Charan is an much younger than Raju as he is older than Tharun. If the sum of the ages of Raju and Tharun is 50 years, what is definitely the difference between Raju and Charan's age?
A.) 4 years
B.) 5 years
C.) 3 years
D.) Data inadequate

Answer: Option 'D'

Given that
1. The difference of age between Raju and Charan = The difference of age between Charan and Tharun.
2. Sum of age of Raju and Tharun is 50 i.e (Raju + Tharun) = 50
Question : Raju - Charan = ?
Solution : 
Raju - Charan  = Charan - Tharun
(Raju + Tharun) = 2Charan 
Now given that, (Raju + Tharun) = 50
So, 50 = 2Charan and therefore Charan = 25.
The question is (Raju - Charan) = ?
Here we know the value (age) of Charan(25), but we don't know the age of Raju.
Therefore, (Raju - Charan) cannot be determined

  • 3. Vamsi started a company investing Rs. 200000. After 8 months, Krishna joined him with a capital of Rs. 120000. After 2 years, they earned a profit of Rs. 42000, what is Krishna's share of the profit?
A.) Rs. 14,000/-
B.) Rs. 13,000/-
C.) Rs. 12,000/-
D.) Rs. 11,000/-

Answer: Option 'C'

Profits of Vamsi and Krishna are in the ratio 200000 × 24 : 120000 × 16 = 5 : 2
Krishna's share = (2/7) × 42000 = Rs. 12000/-

  • 4. How many seconds will a 500 meter long train moving with a speed of 63 km/hr, take to cross a man walking with a speed of 3 of 3 km/hr is the direction of the train?Latest model Quant Questions for SBI PO - Practice Test 1
A.) 43
B.) 30
C.) 54
D.) 28

Answer: Option 'B'

Distance = 500m
Speed = 63 - 3 km/hr = 60 km/hr
= 600/36 m/s = 50/3 m/s
Time taken = distance/speed = 500/(50/3) = 30 sec

  • 5. A shopkeeper sells 1 kg of apples for Rs. 160 at a loss of 20%. At what price should he sell a kg of apples to gain 20%?
A.) Rs. 260/-
B.) Rs. 200/-
C.) Rs. 220/-
D.) Rs. 240/-

Answer: Option 'D'

Let the cost price be Rs. (160 + x) Loss = Rs. x Loss% = (x/160+x)) × 100 = 20%
x = Rs. 40 
Cost Price = Rs. 200 Gain% = (Gain/ Cost Price) × 100 = 20% Gain = Rs. 40
Selling Price = Gain + Cost Price = Rs. 240/-
