Options
(a) 5:2
(b) 7:3
(c) 9:2
(d) 13:4

Answer: Let sons age 10 years ago = x.

Then, fathers age 10 years ago = 3x.

2(x+ 10+ 10) = (3x + 10 + 10)so x = 20.

Ratio of their present ages = (3x + 10) : Cx + 10) 70: 30 = 7 :3

Question 2: A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?

Options
(a) 65 sec
(b) 89 sec
(c) 100 sec
(d) 150 sec

Question 4: By selling 45 lemons for Rs 40, a man loses 20 %. How many should he sell for Rs 24 to gain. 20 % in the transaction ?

Options
(a) 16
(b) 20
(c) 22
(d) 18

Answer: Let S.P. of 45 lemons is Rs. x.
$80:40=120:x\, or\, \frac{80}{40}=\frac{120}{x}\, or\, x=40\times \frac{120}{80}=60$
lemons sold For Rs. 60, = 45
lemons sold For Rs. 24, = $\left ( \frac{45}{60} \right )\times 24=18$

Question 5: The average of seven consecutive odd numbers is 47. What is the greatest number among these seven numbers?

Options
(a) 35
(b) 52
(c) 53
(d) 63
(e) None of these

Answer: Let the seven consecutive odd numbers be x, x + 2, x + 4, x + 6, x + 8, x + 10, x+12.

$\therefore$ $\frac{x + (x + 2) + (x + 4) +....+ (x + 12)}{7}\:\:= 47$

$\Rightarrow$ 7x + 42 = 329

$\Rightarrow$ 7x = 287

$\Rightarrow$ x = 41

So, the greatest number = (41 + 12) = 53

Question 6: The simple interest and the true discount on a certain sum for a given time and at a given rate Rs.85 and Rs.80 respectively.The sum is :

Options
(a) Rs.1500
(b) Rs.1486
(c) Rs.1360
(d) Rs.8921

Answer: sum=$\frac{S.I.\times T.D.}{(S.I)-(T.D.)}=\frac {85\times 80}{(85-80)}=Rs.1360$

Question 7: What value will replace the question mark in the following equations?
5172.49 + 378.352 + ? = 9318.678

Options
(a) 3567.836
(b) 3667.836
(c) 3767.83
(d) 3867.836

Answer: Let 5172.49 + 378.352 + x = 9318.678.

Then, x = 9318.678 – (5172.49 + 378.352)

=> 9318.678 – 550.842

=> 3767.836.

Question 8: If log 2 = 0.3010 and log 3 = 0.4771, the value of log5 512 is:

Options
(a) 0.876
(b) 2.456
(c) 3.876
(d) 5.456

Answer: $log_{5}$ 512 = $\frac{log 512}{log 5}$

$\frac{9 log 2}{log 10 -log 2}$

= $\frac{9\times 0.3010}{1-0.3010}$

= $\frac{2.709}{0.699}$

= $\frac{2709}{699}$

= 3.876

Question 9: The third proportional to 0.36 and 0.48 is :

Options
(a) 0.64
(b) 0.1728
(c) 0.42
(d) 0.94

Answer: Let the third proportional to 0.36 and 0.48 be x

Then, 0.36 : 0.48 :: 0.48 : x

$\Rightarrow \left ( \frac{0.48\times 0.48}{0.36} \right )=0.64$

Question 10: Two taps X and Y can fill a tank in 2.5 hours and 10 hours respectively. If both the taps are open then due to a leakage, it look 30 minutes more to fill the tank. If the tank is full, how long will it take for the leakage alone to empty the tank?

Options
(a) 5 hrs
(b) 10 hrs
(c) 15 hrs
(d) 25 hrs

Answer: Part filled by (X + Y) in 1 hour = $\frac{1}{2.5}+\frac{1}{10}=\frac{1}{2}$

So, X and Y together can fill the tank in 2 hours.

$\therefore$ Leak will empty the tank in 10 hour
