Question 1: The average age of 12 students is 20 years if the age of one more student is included, the average decreases by 1. What is the age of the new student?. [Bank P.O. 1991]

(a) 5 years
(b) 9 years
(c) 7 years
(d) 11 years

Answer: New average = (20 - 1) = 19.

Age of new student = (13 χ 19 - 12 χ 20) years = 7 years

Question 2: A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

(a) 230 m
(b) 260 m
(c) 240 m
(d) 270 m

Answer: Speed=\left ( 72\times \frac{5}{18} \right )m/sexc=20\, \,m/sec

Time = 26 sec.

Let the length of the train be x metres.

Then,\, \, \frac{x+250}{26}=20

x + 250 = 520

x = 270.

Question 3: A can finish a job in 15 days and B can do it in 10 days. If they work together then A’s share out of total wages of Rs. 2250 is

(a) Rs. 1350
(b) Rs. 900
(c) Rs. 1025
(d) Rs. 1125

Answer: A : B =  \frac{1}{15}: \frac{1}{10}=10:15

A’ share = \frac{10}{10+15} \times 2250 =900

Question 4: The average temperature on Tuesday, Wednesday and Thursday was 37 C. The average temperature on Wednesday, Thursday and Friday was 38 C. If the temperature on Friday was 39 C, find the temperature on Tuesday.

(a) 35 C
(b) 36 C
(c) 39 C
(d) 42 C
(e) None of these

Answer: Tuesday + Wednesday + Thursday = 37 \times3

Friday + Wednesday + Thursday = 38\times3

\therefore\,\,Friday - Tuesday = 3 (38 - 37)

\Rightarrow\,\,39 - Tuesday = 3

\Rightarrow\,\,Tuesday = 36

\therefore\,\,Temperature\, \,on\, \,Tuesday =36^{o}C

Question 5: A bag contains 4 white, 5 red and 6 blue balls. Three balls are drawn at random from the bag. The probability that all of them are red, is: (I. B)

(a) \frac{2}{98}
(b) \frac{1}{98}
(c) \frac{2}{68}
(d) None of these

Answer: let S be the sample space.

Then, n(S) = number of ways of drawing 3 balls out of 15

= 15c_{3}

= \frac{15\times 14\times 13}{3\times 2\times 1} = 455

Let E = event of getting all the 3 red balls.

= \therefore n(E)=5C_{3}=5C_{2}=\frac{5\times 4}{2\times 1} = 10

= \therefore P(E)=\frac{N(E)}{N(S)}=\frac{10}{455}=\frac{2}{98}

Question 6: The salaries of A, B and C are of ratio 2:3:5. If the increments of 15%, 10% and 20% are done to their respective salaries, then find the new ratio of their salaries.

(a) 20:33:60
(b) 20:33:60
(c) 22:33:60
(d) 23:33:60
(e) 23:33:60

Answer: Let A salary be 2x, B is 3x and C salary be 5x

A's new slary be=\frac{115}{100}\times 2k=\frac{23}{10}k

B's new slary be=\frac{110}{100}\times 3k=\frac{33}{10}k

C's new slary be=\frac{120}{100}\times 5k=6k

New ratio=\frac{23}{10}k:\frac{33}{10}k:6k

= 23: 33: 60

Question 7: The smallest number which when diminished by 3 is divisible by 21, 28, 36 and 45 is

(a) 1234
(b) 1263
(c) 1257
(d) 1287

Answer: Number =(L.c.m. of 21, 28, 36, 45) + 3 = 1263.

Question 8: A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is: (railway 2002)

(a) 6 hrs
(b) 10 hrs
(c) 15 hrs
(d) 20 hrs

Answer: Suppose, first pipe alone takes x hours to fill the tank .

Then, second and third pipes will take (x -5) and (x - 9) hours respectively to fill the tank.

\therefore \frac{1}{x}+\frac{1}{x-5}=\frac{1}{x-9}

x - 5 + x = 1

x(x - 5) (x - 9) = 1

(2x - 5)(x - 9) = x(x - 5)

(x - 15)(x - 3) = 0

x = 15. [neglecting x = 3]

Question 9: A can run 22.5 m while B runs 25 m. In a kilometre race B beats A by

(a) 50 m
(b) 75 m
(c) 100 m
(d) none of these

Answer: When B runs 25 m, A runs \frac{45}{2}m

When B runs 1000 m, A runs (\frac{45}{2}\times \frac{1}{25}\times 1000)

B beats A by 100 m.

Question 10: What was the day on 13th April 1999?

(a) Sunday
(b) Monday
(c) Tuesday
(d) Wednesday

Answer: 13th April, 1999 = (1998 years + Period from 1.01.199 to 13.04.1999)

Counting of odd days:

Numbers of odd days in 1600 years = 0.

Numbers of odd days in 300 years = (5 × 3) = 15 = 1.
(When 15 is divided by 7, it gives 1 as the remainder.)

98 years = (24 leap year + 74 ordinary years) ⇒ (24 × 2 + 74 × 1) = (48 + 74) = 122 days.

⇒ 122 days = (17 weeks + 3 day) = 3odd days

∴ 1998 years have = (0 + 1 + 3) = 4 odd days.

Jan Feb Mar April
31 + 28 + 31 + 13 = 103 days

⇒ 103 days = (14 weeks + 5 days) = 5 odd days

∴ Total number of odd days = (5 + 4) = 9 = 2.

Hence, the required day is Tuesday.

Question 19: 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. It is the fault of the English to expect the people of other countries to react as they do, to political and international situations. Our genuine goodwill and good intentions are often brought to nothing, because we expect other people to be like us. This would be corrected if we knew the history, not necessarily in detail but in broad outlines, of the social and political conditions which have given to each nation its present character.

According to the author of 'Mentality' of a nation is mainly product of its

(a) history
(b) international position
(c) politics
(d) present character
