Question 1: Ratio of Ashoks age to Sandeeps age is 4 : 3. Ashok will be 26 years old after 6 years. How old is Sandeep now? [Railways 1989]

Options
(a) 12 years
(b) 19 years
(c) 15 years
(d) 21 years

Answer: Let their ages be 4x and 3x years.

Now 4x + 6 = 26 hence x = 5

So Age of Sandeep = 3x = 15 years

Question 2: A train overtakes two persons who are walking in the same direction in which the train is going, at the rate of 2 kmph and 4 kmph and passes them completely in 9 and 10 seconds respectively. The length of the train is:

Options
(a) 45 m
(b) 54 m
(c) 50 m
(d) 72 m

Answer: $2\, kmph=\left ( 2\times \frac{5}{18} \right )m/sec=\frac{5}{9}m/sec$

$4\, kmph=\left ( 4\times\frac{5}{18} \right )m/sec=\frac{10}{9}m/sec$

Let the length of the train be x metres and its speed by y m/sec

$Then,\, \left (\frac{x}{y-\frac{5}{9}} \right )=9 \, \, and\, \,\left (\frac{x}{y-\frac{10}{9}} \right )=10$

9y - 5 = x and 10(9y - 10) = 9x

9y - x = 5 and 90y - 9x = 100.

On solving, we get: x = 50.

Length of the train is 50 m.

Question 3:A boat running downstream covers a distance of 16 km in 2 h while covering the same distance upstream it trake 4 h. What is the speed of the boat in still water?

Question 4: The average age of 60 boys in a class was calculated as 12 yr. It was later realised that the actual age of one of, the boys in the class was 12.5 yr but it was calculated as 14 yr. What is the actual average age of the boys in the class?

Options
(a) 11 yr
(b) 11.275 yr
(c) 11.50 yr
(d) 11.975 yr
(e) none of these

Answer: Actual average age = $\frac{60 x 12 - (14 - 12.5)}{60}$

= $\frac{720 - 1.5}{60}$

= $\frac{718.5}{60}$ = 11.975 yr

Question 5: A has to pay Rs.220 to B after 1 year.B asks A to pay Rs.110 in cash and defer the payment of Rs.110 for 2 years. A agrees to it. If the rate of interest be 10% per annum, in this mode of payment :

Options
(a) There is no gain or loss to any one
(b) A gains Rs.7.34
(c) A loses Rs.7.34
(d) A gains Rs 11

Answer: A has to pay= P.W. of Rs.220 due 1 year hence=Rs. $(\frac{220\times 100}{100+(10\times 1)}$ )= Rs.200.

A actually pays=Rs.110+P.W.of Rs.110 due 2 years hence

= $(110+\frac{110\times 100}{100+(10\times 2)}$ )= Rs.192.66

$\therefore$ A gains= =Rs.(200-192.66)=Rs.7.34

Question 6: If $a^{x}=b^{y}$ , then : ( Bank p.o 2003)

Options
(a) x
(b) y
(c) x:y
(d) y:x
(e) None of these

Answer: $a^{x}=b^{y}$

$\Rightarrow loga^{x}=logb^{y}$

$\Rightarrow$ x log a = y log b

$\Rightarrow \frac{loga}{log b} =\frac{y}{x}$

Question 7: The ratio of present ages of A and B is 4:5 and after 5 years it will be 5:6. What is the present age of A?

Options
(a) 10 years
(b) 20 years
(c) 25 years
(d) 40 years

Answer: Present age of A= $4\times 5\frac{\left ( 6-5 \right )}{21-20}=20\,\,years$

Present age of B= $5\times 4\frac{\left ( 6-5 \right )}{21-20}=20\,\,years$

Question 8: The greatest number which on dividing 42, 49 and 56 will leave 6,7 and 8 respectively as remainder, is.

Options
(a) 3
(b) 4
(c) 5
(d) 6
(e) None of these

Answer: The greatest number

= HCF of (42 - 6), (49 - 7) and (56 - 8)

= HCF of 36, 42 and,48

= 6

Question 9: Two pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is: (S.B.I.2002)

Options
(a) 120 gallons.
(b) 150 gallons.
(c) 170 gallons.
(d) 190 gallons.

Answer: Work done by the waste pipe in 1 minute =$\frac{1}{15}-(\frac{1}{20}+\frac{1}{24})$

$\frac{1}{15}-\frac{11}{120}$

$-\frac{1}{40}$ [-ve sign means emptying]

$\therefore Volume of \frac{1}{40}$ part = 3 gallons

Volume of whole = (3 x 40) gallons = 120 gallons.

Question 10: The banker's gain of a certain sum due 2 years hence at 10% per annum is Rs.24.The present worth is :

Options
(a) Rs.350
(b) Rs.420
(c) Rs. 600
(d) Rs. 863

Answer: T.D=$(\frac{B.G.\times 100}{Rate\times Time})=Rs.(\frac{24\times 100}{10\times 2})= Rs. 120$

$\therefore$ P.W.=$\frac{100\times T.D}{Rate\times time}= Rs.(\frac{100\times 120}{10\times 2})Rs.=600$

Question 18: Laws of nature are not commands but statements of acts. The use of the word "law" in this context is rather unfortunate. It would be better to speak of uniformities in nature. This would do away with the elementary fallacy that a law implies a law giver. If a piece of matter does not obey a law of nature it is punished. On the contrary, we say that the law has been incorrectly started.

If a piece of matter violates nature's law, it is not punished because

Options
(a) it is not binding to obey it
(b) there is no superior being to enforce the law of nature
(c) it cannot be punished
(d) it simply means that the facts have not been correctly stated by law

Answer: there is no superior being to enforce the law of nature.
