Question 1: The sum of the ages of a father and son is 45 years. Five years ago, the product of their ages was four times the fathers age at that time. The present age of father and son, respectively are:. [Hotel Management]

Options
(a) 25 years, 10 years
(b) 39 years, 6 years
(c) 36 years, 9 years
(d) None of these

Answer: Let sons age = x years. Then fathers age = (45 - x)years.

(x—5)(45—x—5) = 4(45- x- 5) hence (x—5) = 4 so x = 9

Their ages are 36 years and 9 years.

Question 2: Two trains of equal lengths take 10 seconds and 15 seconds respectively to cross a telegraph post. If the length of each train be 120 metres, in what time (in seconds) will they cross each other travelling in opposite direction?

Options
(a) 10
(b) 15
(c) 12
(d) 20

Answer: $Speed\, of \,the\,first\,train =\frac{120}{10}m/sec=12\, m/sec$

$Speed\,of\,the\, second\,train =\frac{120}{15}m/sec=8\, m/sec$

Relative speed = (12 + 8) =20 m/sec.

Required time =$\left [ \frac{\left ( 120+120 \right )}{20} \right ]sec=12\,sec$

Question 3: 30 men and 14 boys can reap a field in 121 days. If 3 men do as much work as 5 boys then 20 men and 4 boys will receipt in

Options
(a) 18 days
(b) 27 days
(c) 26 days
(d) None of the above

Answer: $\frac{30}{m}+ \frac{40}{b} =\frac{1}{21}$ …… (i)

$3 \times \frac{1}{m} = 5 \times \frac{1}{b}$

$\Rightarrow \frac{1}{m}= \frac{5}{3b}$

Substituting in (i)

We get $\frac{1}{b}= \frac{1}{1050}\:and\: \frac{1}{m}= \frac{1}{630}$

Work done by 20 men and 4 boys in 1 day

= $\frac{20}{630}+\frac{4}{1050}= \frac{13}{315}$

Hence work will be over in $\frac{315}{13}=24 \frac{3}{13}\:days$

Question 4: A shop of electronic goods is closed on Monday. The average sale per day for the remaining six days of a week is Rs. 15640. If the average sales from Tuesday to Saturday is Rs. 14124, what is the sales on Sunday?

Options
(a) Rs. 21704
(b) Rs. 23220
(c) Rs. 20188
(e) None of these

Answer: The Sales on Sunday = $6 \times15640 - 5 \times14124$

= (93840 - 70620)

= Rs. 23220

Question 5: A jar contains 3 red marbles, 7 green marbles and 10 white marbles. If a marble is drawn from the jar at random, what is the probability that this marble is white?

Options
(a) $\frac{1}{2}$
(b) $\frac{2}{3}$
(c) $\frac{2}{5}$
(d) none of these

We first construct a table of frequencies that gives the marbles color distributions

as follows

Color frequency

red 3

green 7

white 10

We now use the empirical formula of the probability

$\frac{Frequency\, for\, white\, color}{Total\: frequencies\: in \: the\: above \: table}$

P(E) = 10 / 20 = 1 / 2

Question 6: If a+b : b+c : c+a = 6 : 7 : 8 and a + b + c = 14, then the value of c is :

Options
(a) 6
(b) 8
(c) 7
(d) 14

Answer: (a/3) = (b/4) = (c/7) then a = 3k, b = 4k, c = 7k

a+b+c/c = 3k+4k+7k/7k = 14k/7k = 2

Question 7: Three numbers are in the ratio 1: 2 : 3 and their H.C.F. is 12. The numbers are: . [C. B. I. 1991]

Options
(a) 12, 24, 36
(b) 5, 10, 15
(c) 10, 20, 30
(d) 4, 8 12

Answer: Let the required numbers be z, 2z and 3z. Then, their H.C.F. = z. So, z = 12.

The numbers are 12, 24 and 36.

Question 8: Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes, and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, and C discharge chemical solutions P,Q and R respectively. What is the proportion of the solution R in the liquid in the tank after 3 minutes? (C.B.I 2000)

Options
(a) $\frac{6}{11}$
(b) $\frac{8}{11}$
(c) $\frac{9}{11}$
(d) None of these

Answer: Part filled by (A + B + C) in 3 minutes = $3(\frac{1}{30}+\frac{1}{20}+\frac{1}{10})=3\times \frac{11}{16}=\frac{11}{20}$

Part filled by C in 3 minutes = $\frac{3}{10}$

Required ratio = $\frac{3}{10}\times \frac{20}{11}=\frac{6}{11}$

Question 9: At a game of billiards, A can give B 15 points in 60 and A can give C to 20 points in 60. How many points can B give C in a game of 90? ( p.o 2000)

Options
(a) 5
(b) 10
(c) 15
(d) 20

Answer: A : B = 60 : 45.

A : C = 60 : 40. $\frac{B}{C}=(\frac{B}{A}\times \frac{A}{C})=(\frac{45}{60}\times \frac{60}{40})$

B can give C 10 points in a game of 90.

Question 10: What day was it on 1st Jan 2004?

Options
(a) Tuesday
(b) Monday
(c) Saturday
(d) Thursday

Answer: 1st Jan, 2004 = (2003 years + 1.01.2004)

Counting of odd days:

Numbers of odd days in 2000 = 0

Numbers of odd days in 3 ordinary years = 3.

Total odd day in year 2003 = (0 + 3) = 3.

Jan
1 = 1 odd day .

Total odd days = (3 + 1) = 4

Hence, the required day is Thursday.
