Question No : 3 The rectangle box with square base is open at the top. The maximum volume of the box made from 1200 m2 tin, in m3 is:
A. 2000 
B. 2500 
C. 3000 
D. 4000 
Let the length be x and the breadth be y. Now since it has a square base; x=y Now the surface area can be given as S= x^2+4xy (Area of square base + Area of Sides) And Volume can be given as V = x^2y ATQ, S=1200,so 1200=X2+4xy y=(1200-x2)/4x Now for V to be max V'=0 V'(x)=x2y Solving for x we get x=20 Now y=20m Hence volume is 20x20x10=4000 m3

Question No : 4 A person was fined for exceeding the speed limit by 10 km/hr. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was travelling at a speed of 35km/hr, find the speed limit.

A. 2000 
B. 4000 
C. 6000 
D. 1000 
Let x be the salary. Then if he spends (2/3)x on rent and food then the remaining salary is x/3, Out of which he spends 1/4 i.e(x/3)1/4 or x/12 on transportation...and the amount left thereafter is : ( x/3 ) - ( x/12 ) = x/4 Given..the amount left with Rajesh is : 6000 = x/4 => Salary of Rajesh 'x' is : 6000 * 4 = Rs.24,000 Amount spent on rent and food = 24000 * (2/3) = Rs.16,000
Remaining amount : 24000 - 16000 = Rs.8000 Amount spent on transportation : 8000 * (1/4) = Rs.2000 Remaining amount : 8000 - 2000 = Rs.6000,the amount left with Rajesh
So answer is : 2000

Question No : 31 A number of cats got together and decided to kill between them 999919 mice. Every cat killed an equal number of mice. Each cat killed more mice than there were cats. How many cats do you think there were ?
A. 991 
B. 992 
C. 993 
D. 994 
Observing the num 999919 which is the total num of rats being eaten, we can write it as
(1000000-81) = (1000^2-9^2) = (1000+9)(1000-9) = (1009)(991)
So total num of rats killed =(1009)(991)
And given that each cat kills more num of rats than the total num of cats
Hence each cat kills 1009 num of rats
And there are 991 num of cats

Question No : 45 A monkey starts climbing up a tree 20ft. tall. Each hour, it hops 3ft. and slips back 2ft. How much time would it take the monkey to reach the top?
A. 17 hours 
B. 18 hours 
C. 19 hours
D. 20 hours 
The first hour, the monkey goes 3 feet up, and slips back 2 feet.
0.1..2..3..4..5..6 |---|---|---|---|---|---| ----------> ....<-----
(Imagine that's going up instead of horizontal.)
So the monkey is 3 ft - 2 ft = 1 ft high after one hour.
In the second hour, the monkey goes up 3 more feet, and slips back 2 feet. So he's at 1 ft + 3 ft - 2 ft = 2 ft.
Every hour, he gains 3 ft and loses 2 ft, for a total gain of 1 ft. So after the 17th hour, he's at 17 ft high.
Now, here's the twist: in the 18th hour, he climbs up 3 feet. Since 17 ft + 3 ft = 20 ft, he's at the top of the tree!
So, it takes him 18 hours.

Question No : 46 What is the missing number in this series? 8 2 14 6 11 _ 14 6 18 12

Question No : 47 A certain type of mixture is prepared by mixing brand A at Rs.9 a kg. with brand B at Rs.4 a kg. If the mixture is worth Rs.7 a kg., how many kgs. brand A are needed to make 40kgs. of the mixture?
A. 24kgs. 
B. 25kgs. 
C. 26kgs. 
D. 27kgs 
A + B = 40.
And at Rs 7 a kg for 40 kg, you want a total of Rs.280.
So the second equation is 9A + 4B = 280
From the first equation: B = 40 - A and sub into the second equation:
9A + 4(40-A) = 280 9A + 160 - 4A = 280 5A = 120 A = 24.
Your answer, of course, is A = 24.

Question No : 52 The minute hand of a clock overtakes the hour hand at intervals of 64 minutes of correct time. How much a day does the clock gain or lose?
A. 31 min and 434/11 sec 
B. 32 min and 434/11 sec 
C. 33 min and 434/11 sec 
D. None of the above 
The minute hand overtakes hours hand 11 times in 12 hours Therefore the time taken by the minute to overtake = (12 * 60)/11= 65.4545 minutes In this clock the minute hand is taking 64 minutes to overtake Therefore in 12 hours it will overtake 720/64 = 11.25 times That means 0.25 times more in 12 hours or 0.5 times more in a day Hence, the clock gains = 0.5 times of the normal time ⇒ 65.4545 * 0.5 = 32.72 minutes or 360/11 minutes
Alternative explanation
Let x be distance traveled by hour hand Then distance traveled by minute hand = 1 + x
Time = Distance/Rate ⇒ x/(1/12) = (1 + x)/1 ⇒ x = (1/12)(1 + x) = 1/12 + x/12 ⇒ (11/12)x = 1/12 x = 1/11
Calculate time for minute hand to travel a distance 1 + x.
Time = Distance/Rate (1 + x)/1 = 1 + x = 1 + 1/11 = 12/11 hour
Actual time to overtake on clock is 64 minutes.
64 min = 64/60 hours = 16/15 hour
Correct Clock Speed/Actual Clock Speed (12/11) / (16/15) = 12*15 / (11*16) = 180/176 = 45/44
The clock gains: 45/44 - 1 = 1/44 day = 24/44 hour = 6/11 hour = 360/11 min = 32 min and 434/11 sec
