Directions for questions 1 to 8: Choose the correct options.
1. A bag contains 14 yellow balls, 5 red balls and 8 green balls. 3 balls are drawn at random one by one. Find out the probability of drawing all 5 yellow balls without replacement.
a)  5/27
b) 14C5/27C5
c) (14/27) x (13/26) x (12/25) x (11/24) x (10/24)
d) 5/(27 x 26 x 25)
Explanation:
Total number of balls = 14+5+8 = 27
First yellow ball drawing probability = total yellow balls/total balls = 14/27
Second yellow ball = (total yellow balls – 1) /(total balls – 1) = 13/26 (As we have already drawn a yellow ball in first turn)
Third Yellow balls = (total yellow balls – 2) / (total balls – 2) = 12/25 and so on
So, probability of drawing 5 yellow balls without replacement=(14/27) x (13/26) x (12/25) x (11/24) x (10/24)
Therefore, correct answer is Option C
2. There are two packets for butter available in market.
Packet A: 200 grams of butter for rupee 124
Packet b: 250 grams of butter for rupee 155
Which is a better deal?
a) Packet A
b) Packet B
c) Both have same value
d) Data insufficient
Explanation:
Packet A: 200 gms = 124 => 1 gms = 124/200
50 gms = (124*50)/200 = Rs. 31
Packet B: 250 gms = 155 => 1 gms = 155/250
50 gms = (155*50)/250 = 31
So, both the options have same value.
Therefore, the correct answer is Option C
3. 14 men can complete a work in 25 days. How many men are required to complete the same work in 15 days? Approximation is accepted
a) 22
b) 24
c) 23
d) 25
Explanation:
Let suppose the work done = number of men * days = 14 * 25 = 350 units
So, number of men required to complete word in 15 days = Total work/number of days = 350/15 = 23.333 ~ 24
Therefore, the correct answer is Option B
4. If X=4 and Y = 12, What is the value of (X+Y)^(Y/X) ?
a) 526
b) 1024
c) 8009
d) 4096
Explanation:
(X+Y)^(Y/X) = 16^3 = 4096
Therefore, the correct answer is Option D
5. 80 litres of salt and water mixture contains 75% salt. Find out the amount of water required to be added to decrease the percentage of salt to 40%.
a) 70 litres
b) 75 litres
c) 80 litres
d) 65 litres
Explanation:
Amount of Salt in 80 litres = 0.75*80 = 60 litres
Now, to decrease the amount of salt in water, let suppose we add X litre of water in the solution
=> 0.4 (X+80) = 60 => 0.4X + 32 = 60
=> 0.4 X= 28 → X = 70 litres
Therefore, the correct answer is Option A

6. The selling price of 10 apples is equal to cost price of 11 apples. Find out the profit/loss percentage.
a) 10% loss
b) 10% profit
c) 100/11% profit
d) 100/11% loss
Explanation:
Let the cost price of an apple = X
Selling price of an apple = Y, As per question → 10 Y = 11 X => Y = (11/10) * X
Profit percentage = [(Selling Price –Cost Price) *100]/Cost Price = [(1.1X-X)*100]/X = 10% profit
Therefore, the correct answer is Option B
7. If the 10th term of an AP is 49 and 14th term of the same AP is 69. Find out first term.
a) 3
b) 6
c) 5
d) 4
Explanation:
Let first term be aand common difference be d.
Now, a + 9d = 49 and a + 13d = 69, on solving these equations
a = 4 and d = 5.
Therefore, the correct answer is Option D
