[fusion_text]Question 1: Pushpa is twice as old as Rita was 2 years ago. If the difference of their ages be 2 years, how old is Pushpa today 7. [Railways 1991]

Options
(a) 6 years
(b) 10 years
(c) 8 years
(d) 12 years

Answer: Let Ritas age 2 years ago = x years.

Pushpas age now = 2x years.

2x- (x + 2) = 2 so x = 4.

Pushpas age now = 8 years

Question 2: Two stations A and B are 110 km apart on a straight line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at 8 a.m. and travels towards A at a speed of 25 kmph. At what time will they meet?

Options
(a) 9 a.m.
(b) 10 a.m.
(c) 10.30 a.m.
(d) 11 a.m.

Answer: Suppose they meet x hours after 7 a.m.

Distance covered by A in x hours = 20x km.

Distance covered by B in (x - 1) hours = 25(x - 1) km.

Therefore 20x + 25(x - 1) = 110

=> 45x = 135

=> x = 3.

So, they meet at 10 a.m.

Question 3: If 3 men or 9 boys can finish a piece of work in 21 days. In how many days can 5 men and 6 boys together do the same piece of work?

(c) 14 days
(d) Cannot be determined
(e) None of these

1 man=3boys

.'. 5 men + 6 boys =(15 + 6) boys =21boys

Now, 9 boys can finish the work in = 21 days

.'. 1 boy can finish the work in =

.'. 21 boys will finish the work in = days

= 9 days

Options
(a) Rs.12,000 in cash
(b) Rs.12,8860 in credit
(c) Rs.14,568 in credit
(d) Both are eqaully good

Answer: P.W. of Rs.12,880 due 8 months hence

=Rs.$\left [\frac{12880\times 100}{100+(18\times \frac{8}{12})}\right ]$=Rs.$(\frac{12880\times 100}{112})$= Rs.11500

Clearly Rs.12,00 in cash in a better offer.

Question 6: if $log_{10}$ 7 = a then $log_{10}(\frac{1}{70})$ is equal to (R.R.B 2000)

Options
(a) (a + b)
(b) - (a+b)
(c) a
(d) b

Answer: $log_{10}(\frac{1}{70})$ = $log_{10} 1 -log_{10} 70$

$log_{10}$ =$log_{10}(7\times 10)$

$(log_{10}7+log_{10}10)$

= - (a + b)

Question 7: What number should be subtracted from both the terms of the ratio 15 : 19 so as to make it as 3 : 4 ?

Option
(a) 3
(b) 6
(c) 5
(d) 9

Answer: Let x be subtracted. Then,

$(15 - x) / (19 - x) = 3/4 \Rightarrow 4(15 - x) = 3(19 - x)$ x = 3

Question 8: A water tank is three-fourth full. Pipe X can fill a tank in 12 minutes and Pipe Y can empty it in 8 minutes. If both the pipes are open, how long will it take to empty or fill the tank completely?

Options
(a) 6 min
(b) 12 min
(c) 18 min
(d) 24 min

Answer: Clearly Y is faster than X

Part to be emptied = $\frac{3}{4}$

Part emptied by (X + Y) = $\frac{1}{8}-\frac{1}{12}=\frac{1}{24}$

$\frac{1}{24}:\frac{3}{4}$:: 1 : x or x =$\frac{3}{4}\times 1\times 24$ = 18 minutes

So, the tank will be emptied in 18 min.

Question 9: Three rods of lengths 15 m, 42 m and 39 m are to be cut into pieces of equal length. What is the greatest possible length of each pieces?

each pieces = HCF of 15 m, 42 m and 39 m

= 3 m
