Question 1: The sum of the ages ofA, B and C is 96 years. To find out B’s age, which of the following information given in the statements P and Q is/are sufficient
P : A is 6 years older than C
Q : The total of B and C’s ages is 56 years.. [Bank P.O. 1994]

(a) P
(b) both P and Q
(c) Q
(d) None of these

Answer: A + B + C = 96. Let C = Χ. Then, A = Χ + 6.

Χ + 6 + B + X = 96 so B + 2Χ = 90

Now B + C = 56 so B+ X = 56

Χ=(90 - 56) = 34.

B+2x = 90 => B = (90 - 68) = 22.

Thus both P and Q are needed.

Question 2: Two trains 200 m and 150 m long are running on parallel rails at the rate of 40 kmph and 45 kmph respectively. In how much time will they cross each other, if they are running in the same direction ?

(a) 72 sec
(b) 132 sec
(c) 192 sec
(d) 252 sec

Answer: Relative Speed = (45 - 40 ) Kmph

= 5 kmph

=(5 x 5 18)m/sec

= (25 18 ) m/sec

Time taken= (350 x 18 / 25) sec

= 252 sec.

Question 3: A and B together can do a piece of work in 4 days.If A alone can do it in 6 days, l.e. In how many days B can alone complete the same piece of work?

(a) 12
(b) 8
(c) 9
(d) 16
(e) None of these

Answer: B's alone one day work =

.'. B can alone complete the work in 12 days.

Question 4: Goods were bought for Rs.600 and sold the same day for Rs.688.550 at a credit of 9 months and thus gaining 2%. The rate of interest per annum is :

(a) 20%
(b) 25%
(c) 30%
(d) None of these

Answer: S.P.=102% of Rs.600= Rs.(\frac{102}{100}\times 600)=Rs.612

Now,P.W.=Rs.612 and sum=Rs.688.50.

 \therefore S.I. on Rs.612 for 9 months is Rs.76.50.

\therefore Rate= (\frac{100\times 76.50}{612\times \frac{3}{4}})% = 16\frac{2}{3}%

Question 5: (log_{10}2) = 0.3010, then , (log_{2}10) is equal to: (railway 2002)

(a) 100
(b) 150
(c) 200
(d) None of these

Answer: (log_{2}10) = \frac{1}{log_{10}2} =\frac{1}{0.3010} =\frac{10000}{3010} =\frac{1000}{301}

Question 6: 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 7: The salaries of A, B, C are in the ratio 2 : 3 : 5. if the increments of 15%, 10% and 20% are allowed respectively in their salaries, then what will be the new ratio of their salaries?

(a) 3 : 3 : 10
(b) 10 : 11 : 20
(c) 23 : 33 : 60
(d) Cannot be determined

Answer: Let A = 2k, B = 3k and C = 5k.

A's new salary=\frac{115}{100}of\, \, 2k=\left ( \frac{115}{100}\times 2k \right )=\frac{23}{10}k

B's new salary=\frac{110}{100}of\, \, 3k=\left ( \frac{110}{100}\times 3k \right )=\frac{33}{10}k

C's new salary=\frac{120}{100}of\, \, 5k=\left ( \frac{120}{100}\times 5k \right )=6k

\therefore\,new\, \,ratio\frac{23k}{10}:\frac{33k}{10}:6k=23: 33: 60

Question 8: Four drums containing water have capacities 135 L, 205 L, l-65 L and 240 L. The greatest capacity measure which can be used to measure the capacities of the drums is.

(a) 2 L
(b) 3 L
(c) 4 L
(d) 5 L
(e) None of these

Answer: The greatest capacity measure = HCF of 135 L, 205 L, 165 L and 240 L = 5 L

Question 9: One pipe can fill a tank four times as fast as another pipe. If together the two pipes can fill the tank in 24 minutes, then the slower pipe alone will be able to fill the tank in:

(a) 60 min
(b) 80 min
(c) 120 min
(d) 145 min

Answer: Let the slower pipe fill the tank in z minutes.

Then, faster pipe will fill it in z/4 minutes.

\frac{1}{z}+\frac{4}{7}=\frac{1}{24}z = 120 min

Question 10: The banker's discount on a sum of money for 1\frac{1}{2} years is Rs.558 and the true discount on the same sum for 2 years is Rs.600.The rate percent is :

(a) 10%
(b) 14%
(c) 12%
(d) 18%

Answer: B.D. for \frac{3}{2} years.= Rs.558. B.D. for 2 years = Rs.(558\times \frac{2}{3}\times 2)= Rs.774

T.D. for 2 years =Rs.600.

\therefore sum=(\frac{B.D.\times T.D }{B.D.-T.D})=Rs.(\frac{744\times 600}{144})=Rs.3100

Thus, S.I.on Rs.3100 for 2 years.

\therefore Rate=(\frac{100\times 744}{3100\times 2})\%= 12\%

Question 18: Harold a professional man who had worked in an office for many years had a fearful dream.

Harold suddenly realised that he himself was covered with these things, and he woke up screaming. In a vivid sequence of pictures this dream dramatised for Harold what he had never been able to put in to words; he saw himself as letting society feed on his body in his early years so that it would carry him when he retired.
