Q 1 - The velocities of A and B are in the proportion 3:4. A takes 20 min. more than B to achieve a destination. In what time does A achieve the destination?
Answer : A
Explanation
Let the time taken by A be x hrs. Then, time taken by B = (x-20/60) hrs = (x-1/3) hrs Ratio of speeds = inverse ratio of time taken ∴3:4 =(x- 1/3): x ⇒3x-1/3x = 3/4 ⇒12x- 4 = 9x ⇒3x= 4 ⇒x= 4/3 hrs Required time = 4/3 hrs.
Q 2 - A man loses Rs 55.50 yearly when the yearly rate of interest tumbles from 11.5% to 10%. His capital is:
Answer : A
Explanation
Let the capital be Rs. x. then, (x*23/2*1/100*1) ?(x*10*1/100*1) = 55.50 => 23x/200 ?x/10 =111/2 => 23x-20x =11100 => 3x= 11100 => x = 3700 Hence, the capital is Rs. 3700.
Q 3 - In a class, the no. of young women is 20% more than that of the young fellows. The class' quality is 66. If 4 more young women are admitted to the class, what will be the no's extent of young fellows to that of the young women?
Answer : C
Explanation
Let the number of boys be x. Then the no. of girls = 120% of x = (120/100 *X)= 6X/5 . X+6x/5 =66 => 5x+6x=330 => 11x= 330 => x= 3 Now, the no. of boys= 30 , no. of girls =[6/5*30 +4]=40 Now the ratio of boys and girls = 30/40 = 3/4 =3:4
Answer : A
Explanation
y = 12846 x 593 + 12846 x 407 = 12846 x (593 + 407) = 12846 x 1000 = 12846000
Q 5 - The captain of a cricket team of 11 members is 26 years old and the wicket keeper is 3 years older. If the ages of these two are excluded the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team?
Answer - B
Explanation
Let the average age of the whole team be z years. Therefore 11z - (26 + 29) = 9 (z - 1) = 11z - 9z = 46 = 2z = 46 = z = 23 So, average age of team is 23 years.
Q 6 - A boat running upstream takes 8 hours 48min to cover a certain separation, while it takes 4 hour to cover the same separation running downstream. What is the proportion between the velocity of the vessel and the velocity of water flow respectively?
Answer : C
Explanation
Let the speed of boat be x km /hr and speed of stream be y km/hr.`44/5 * (x-y) = 4 * (x+y) => 44(x-y) =20 (x+y) => 11 (x-y) = 5(x+y) => 6x=16y`=> x/y= 16/6 = 8/3 => x: y = 8:3.
Q 7 - If the true discount on sum due 3 years hence at 10% per annum be Rs. 180, the sum due is
Answer : A
Explanation
Present worth=( 100*TD)/R*T=( 100 *180 )/10*3=Rs.600.
Q 8 - An aeroplane when 750 m high passes vertically above another aeroplane at an instant when their angles of elevation at same observing point are 45° and 30&de; respectively. Approximately, how many meters higher is the one than the other?
Answer : C
Explanation
Let C and D be the position of the aeroplanes. Given that CB = 900 m,∠CAB = 60°,∠DAB = 45° From the right △ ABC, Tan45=CB/AB=>CB=AB From the right △ ADB, Tan30=DB/AB=>DB=ABtan30=CBx(1/√3)=750/√3 CB=CD+DB => Required height CD=CB-DB=750-750/√3=250(3- √3)

Q 9 - What is the estimated % benefit of the year 2004, if the wage of that year was Rs. 120 crores?
Answer - B
Explanation
Required % gain in 2004 = (50/120*100)% = 47%
Q 10 - If we have two companies A and B . If no. of employess tansfered from A to B , then numbers of employees becomes equal . On the other hand if 20 employees are transferred from B to A Then the number of employess in A becomes doubles in the comparision to B company. How much Employees are working in A's company?
Answer : D
Explanation
We assume that x employee in the A company and y in the B company. Then, (x-10) = ( y+10) ⇒ x- y = 20 ... (i) 2 ( y-20) = (x+20) ⇒ 2y-x = 60 ...(ii) On solving (i) and (ii) , we get x = 100 ∴ There are 100 employees in company A.
