### Practice Questions:

Question 1. The mean of a set of data is 5. What will be the mean if ten is subtracted from each data?

a)5

b)10

c)-5

d)-10

Explanation: let the number of data be n
so sum of data =mean\times number of data mean ×number of data
= 5n
now 10 is subtracted to each data
so now sum becomes = 5n-10n =-5n
mean = sum of data /no. of data
= n−5n​
= -5
so new mean becomes -5

Question 2. In a certain code language if EXTREME = 97 and SEVEN = 70 then CLOCK = ?

a)25

b)84

c)49

d)90

Explanation:
In this the sum of the place values is added to the number of letters in the word and given as its value.
Sum of place values of EXTREME =5 + 24 + 20 + 18 + 5 + 13 + 5 = 90 and 90 + 7 = 97
Sum of place values of SEVEN = 19 + 5 + 22 + 5 + 14 = 65 and 65 + 5 = 70
Similarly, Sum of place values of CLOCK = 3 + 12 + 15 + 3 + 11 = 44 and 44 + 5 = 49

Question 3. With what value should the highest quantity in the data : 65, 52, 14, 26, 18, 35, 32, 38 be replaced so that the mean and medium become equal?

a)40

b)50

c)53

d)67

Explanation: Let’s sort the given data – 14, 18, 26, 32, 35, 38, 52, 65

mean = 35

median=32+35/2​
=33.5

Difference = 35 – 33.5 = 1.5

Value = 1.5 *8 = 12

65-12 = 53

Question 4. A pipe can fill a cistern in 16 hours. After 1/4 the cistern is filled, three more similar pipes are opened. What is the total time taken to fill the cistern completely?

a)4 hours

b)9 hours

c)7 hours

d)None of the above

Explanation: One pipe can fill the cistern in 16 hours
Amount of work done by a pipe in 1 hour = 1/16
Amount of work done by a pipe in 4 hour = 1/4
Therefore ¼ of the work is done by a pipe alone in : 4 hours ………(1)
Work left after 1/4th of the cistern is filled = ¾
Work done by 4 pipes together in 1 hour = 4/16 = 1/4
Work done by 4 pipes together in 3 hour = ¾
Therefore ¾ of the work is done by 4 pipes in : 3 hours …………(2)
Total time taken to fill the cistern completely = 7 hours

Question5. If the mean of the data 5,7,10,14,x,25,32,19 is x, then what is the value of x?

a)14

b)16

c)18

d)20

Explanation: Mean= number of observations/sum of observations.

x= 5+7+10+14+x+25+32+19/8

112+x=8x
7x=112
x=16

Question 6. FPR, GPT, HPV, IPX What is the next word ?

a) EPY

b) JQZ

c) JPY

d) JPZ

Explanation: The first letters are in alphabetical order F,G,H,I so the next letter will be J
The second letter is constant P
In a third letter, there is a gap of one in the alphabetical series R, T, V, X, So the next letter will be Z
So, the next word becomes: JPZ

Question 7. How many liters of a 90% solution of concentrated acid needs to be mixed with a 75% solution of concentrated acid to get a 30 liter solution of 78% concentrated acid?

a) 6

b) 7

c) 8

d) 9

Explanation: The concentration is given which is wrt 100, hence we can take x lt of90% and (30-x)of 75%
x*90 + (30-x)*75 = 30*78

x = 6 ltr

Question 8. Rajeev buys goods worth Rs 7000. He gets a rebate of 6% on it. After getting the rebate, he pays sales tax @10%. Find the amount he will pay for the goods.

a) 7238

b) 7300

c) 7200

d) 7569

Explanation: Rebate = 6% of Rs 7000 = Rs \frac{6}{100} \times 7000 = Rs 420

Sales tax = 10% of Rs (7000 – 420) = Rs \frac{10}{100} \times 6580 = Rs 658

Final amount = Rs (6580 + 658) = Rs.7238

Question 9. A team won 80% of the games it played. It played 5 more games of which it won 3 and lost 2. Its loss percentage changed to 25%. How many games did it play overall?

a) 14

b) 16

c) 20

d) 25

Explanation: if game played=x

then lost game=20% of x =x/5

now they played 5 more games in which they lost 2
so, (x+5)*25%=x/5+2
x=15
so total game he played=15+5 = 20

Question 10. There are five boxes in a cargo hold. The weight of the first box is 200 kg and the weight of the second box is 20% higher than the weight of the third box, whose weight is 25% higher than the first box’s weight. The fourth box at 350 kg is 30% lighter than the fifth box. Find the difference in the average weight of the four heaviest boxes and the four lightest boxes.

a) 45

b) 55

c) 65

d) 75

Explanation:

weight of 1st box=200 kg
weight of 3rd box = 200 + 25% of 200 = 250 kg
weight of 2nd box = 250 + 20% of 250 = 300 kg

weight of 4th box = 350 kg
weight of 5th box = 350 + 30% of 350 =500 kg
avg weight of four heaviest boxes= 1400/4=350 kg
and avg weight of four lightest box=1100/4=275 kg
diff=350 – 275= 75 kg
