Q 1 - Two train approach one another at 30 km/hr and 27 km/hr from two spot 342 km separated. After how long will they meet?
Answer : B
Explanation
Suppose the two trains meet after x hours. Then, 30x+27 x= 342 ⇒ 57 x = 342 ⇒ x = 342/57 = 6. So the two trains will meet after 6 hours.
Q 2 - A man and a kid finish a work together in 24 days. On the off chance that throughout the previous 6 days man alone takes every necessary step then it is finished in 26 days. To what extent the kid will take to complete the work done?
Answer : D
Explanation
Work done by (man + boy ) in 20 days = (1/24*20)= 5/6
Remaining work = (1-5/6) = 1/6
1/6 work is done by boy in 6 days.
Whole work will be done by the boy in (6*6) = 36 days
Q 3 - A vendor bought toffees at 8 for one rupee. How many for a rupee must he sell to gain 25%?
Answer : D
Explanation
C.P. of 8 toffees = Re. 1 S.P. of 8 toffees = 125% of Re. 1 = Rs 1.25=5/4 For Rs5/4 toffees sold = 8. For Re. 1, toffees sold =8x( 5)/( 4)=10.
Answer : B
Explanation
y = 496157 x 9999 = 496157 x (10000 - 1) = 496157 x 10000 - 496157 = 4961570000 - 496157 = 4691100843
Answer : C
Explanation
(x - 0.11) / 1.6 = 1.6 => x = (1.6 x 1.6) + 0.11 = 2.56 + 0.11 = 2.67
Q 6 - A vessel goes 6 km in an hour in still water. It requires thrice as much investment in covering the same separation against the current. Velocity of the current is:
Answer : B
Explanation
Let the speed of the steamer in still water be x km/hr.`Speed downstream = (x +2) km/hr, speed upstream = (x-2) km/hr.`Then 4 (x+2) = 5 (x-2) => x = 18.`Hence, the speed of the streamer in still water is 18 km/hr.

Q 8 - At what time between 4 and 5 o' clock will the hands of a clock be at right angle?
Answer : B
Explanation
At 4 o' clock, the minute hand is 20 minute spaces behind the hour hand. Now, when the two hands are at right angles, they are fifteen min spaces apart. So, they are at right angles in following two cases. Case I ? When the minute hand is 15 min spaces behind the hour hand. In this case, min hand will have to gain (20-15) = 5 min spaces. = (60/55)*5 = 60/11 ∴ They are at right angle at 60/11 minutes past 4. Case II ? When the minute hand is 15 minute spaces ahead of the hour hand. In this case the minute hand will have to gain (20+15) = 35 min spaces. = (60/55)*35 = 420/11 min ∴ They are at right angles at 420/11 min past 4.
Q 9 - A pump can fill a tank with water in 2 hours. In light of a break in the tank, it takes 7/3 hours to fill the tank. The hole can discharge the filled tank in:
Answer : D
Explanation
Part filled by the pump in 1 hr = 1/2 Net part filled by the pump and leak in 1 hr = 3/7 Emptying work done by the leak in 1 hr= (1/2 - 3/7)= 1/14 Leak can empty the tank in 14 hours.
Q 10 - If the average score of boys and girls is 71 and 73 but combined average of boys and girls is 71.8. How much percentage of girls is present in the class?
Answer : A
Explanation
If the number of girls is x than the number of boys in the class (100 -x). Then 73 x+ 71( 100- x) = 71.8 * 100 ⇒ 73x - 71 x = 7180 - 7100 = 2x = 80 ⇒ x = 40 Hence, it proves that 40% girls present in the class.
