Question 1: The average age of an adult class is 40 years. Twelve new students with an average age of 32 years join the class, thereby decreasing the average of the class by 4 years. The original strength of the class was. [Assistant Grade]

Options
(a) 10
(b) 12
(c) 11
(d) 15

Answer: Let, original strength = x.

$\frac{40x + 12\times 32}{x + 12}$ = 36 44

or x = 12

Question 2: Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is:

Options
(a) 1 : 3
(b) 3 : 4
(c) 3 : 2
(d) None of these

Answer: Let the speeds of the two trains be x m/sec and y m/sec respectively.

Then, length of the first train = 27 x metres,

and length of the second train = 17 y metres.

$\therefore \frac{27x+17y}{x+y}=23$

27x + 17y = 23x + 23y

4x = 6y

$\Rightarrow \frac{x}{y}=\frac{3}{2}$

Question 3: A, B and C together do a piece of work for Rs. 5350. A working alone could do it in 5 days, B in 6 days and C in 7 days. The share of C is

Options
(a) Rs. 1500
(b) Rs. 2100
(c) Rs. 1750
(d) None of above

Answer: A : B : C = $\frac{1}{5}: \frac{1}{6}: \frac{1}{7}=42:35:30$

C’s share = $\frac{30}{42+35+30} \times 5350 = 1500$

Question 4: In Ashish’s opinion, his weight is greater than 55 kg but less than 62 kg. His father does not agree with Ashish and he thinks that Ashish’s weight is greater than 50 kg but less than 60 kg. His sister’s view is that his weight can't be greater than 58 kg. If all of them are correct in their estimation, what is the average of different probable weights of Ashish ? (railway 2004)

Options
(a) 58 kg
(b) 56.5 kg
(c) Data inadequate
(d) 43 kg

Answer: Let Ashish weight X kg.

According to Ashish , 55 < X < 62

According to Ashish's father, 50 < X < 60

According to Ashish's sister, X < 58

The values satisfying all the above conditions are 56 & 57.

Therefore, Required average = $\frac{56+57}{2}$=$\frac{113}{2}$

So, the Ashish's weight is 56.5 kg

Question 5: A bag contains 6 black and 8 white balls. One ball is drawn at random. What is the probability that the ball drawn is white?

Options
(a) $\frac{2}{7}$
(b) $\frac{4}{7}$
(c) $\frac{1}{7}$
(d) None of these

Answer: Let number of balls = (6 + 8) = 14.

Number of white balls = 8.

P (drawing a white ball) =$\frac{18}{14}=\frac{4}{7}$

Question 6: Gold is 19 times as heavy as water and copper is 9 times as heavy as water. In what ratio should these be mixed to get an alloy 15 times as heavy as water?

Options
(a) 1 : 1
(b) 2 : 3
(c) 1 : 2
(d) 3 : 2

Answer: Let the weight of gold be x and that of copper is y.

Then from the above condition =>

19x+9y=15(x+y)

Or,4x=6y

Or, $\frac{x}{y}=\frac{3}{2}$

Hence, the ratio of gold and copper should be taken is $\frac{3}{2}$

Question 7: The H.C.f. of 1095 and 1168 is:

Options
(a) 63
(b) 43
(c) 93
(d) 73

Question 8: A runs $1\frac{2}{3}$ times as fast as B. If A gives B a start of 80 m, how far must the winning post be so that A and B might reach it at the same time? (bank p.o 2001)

Options
(a) 100
(b) 150
(c) 200
(d) 250

Answer: Ratio of the speeds of A and B = $\frac{5}{3}$ : 1 = = 5 : 3

Thus, in race of 5 m, A gains 2 m over B.

2 m are gained by A in a race of 5 m.

80 m will be gained by A in race of$\frac{5}{2}\times 80$ m = 200 m

Winning post is 200 m away from the starting point.

Question 9: What was the day on 5th may 2003?

Options
(a) Sunday
(b) Monday
(c) Friday
(d) Saturday

Answer: 5th May, 2003 = (2002 years + Periods from 1.01.2003 to 5.05.2003)

Number of odd days in year 2000 = 0

Number of odd days in 2 ordinary years = 2

∴ 2002 years have = (0 + 2) = 2 odd days

Jan Feb Mar April May

31 + 28 + 31 + 30 + 5 = 125 days

⇒ 125 days = (17 weeks + 6 days) = 6 odd days

Total number of odd days = (2 + 6) = 8 = 1 odd day

It means the required day is Monday.

Question 10: An article costing Rs. 840 was sold at a profit of 50%. The second purchaser sold it once again at a loss of 25%. His selling price was

Options
(a) Rs. 906
(b) Rs. 525
(c) Rs. 945
(d) Rs. 900

Answer: SP of 2nd purchaser = $840 \times \frac{100+50}{100} \times \frac{100-25}{100}$

= $840 \times 1.5 \times 0.75= Rs.945$

Question 18: At this stage of civilization, when many nations are brought in to close and vital contact for good and evil, it is essential, as never before, that their gross ignorance of one another should be diminished, that they should begin to understand a little of one another's historical experience and resulting mentality.

Our genuine goodwill and good intentions are often brought to nothing, because we expect other people to be like us.

(b) Only conclusion 2 follows
(c) Either 1 or 2 follows
