Q 1 - In DAV school, number of boys in a class are four times the number of girls. Which of the following represents the total number of students in the class?
Options :
Answer : A
Explanation
Let the number of girls be x. From question, boys are 4x.Total number of students = x + 4x = 5x. Hence total number of students must be divisible by 5.Hence correct answer is option (A).
Q 2 - In a leading MNC, there are 51 male employees who are over 150 cm tall. If these constitute three-fourths of the male employees and the total number of male employees is two-thirds of the total number of employees in the class, what is the number of female employees in the class?
Options :
Answer : D
Explanation
Let the number of male employees be x. Then, (3/4) x = 51 or x = 51 × (4/3) = 68.If total number of students is y, then (2/3) y = 68 or y = 68 × (3/2) = 72.Therefore Number of females in the MNC = (72 - 68) = 4.
Q 3 - A snail moves up 30 cm when each hour is started and stops for a while when it slips back 20 cm before it again starts climbing in the beginning of the next hour. If it begins its ascent at 8.00 a.m., at what time will it first touch a flower at 120 cm from the ground?
Options :
Answer : B
Explanation
Let the ascent of the snail in 1 hour = ( 30 - 20 ) = 10 cm.
So, the snail ascends 90 cm in 9 hours i.e., 5 p.m.
Clearly, in the next 1 hour i.e., till 6 p.m.
The snail ascends remaining 30 cm to touch the flower.
Q 4 - Two trains are running from Jamshedpur and Kanpur towards each other. Train from Jamshedpur takes 2 hours more than that of the train from Kanpur in covering a distance of 30 km. If Jamshedpur train doubles its speed, then it would take 1 hour less than that of Kanpur. Jamshedpur trains speed is?
Options :
Answer : A
Explanation
Let Jamshedpur train's speed be a km/hr. Then, according to the question if we put it in a mathematical formula then (30/a) (30/2a) = 3
6a = 30
a = 5 km/hr.
Q 5 - Suraj is a businessman and for change note purposes, he went to Reserve Bank and he got Rs. 480 with the values consisting of Rs. 10 notes, Rs. 5 notes, and Rs. 1 notes. The number of notes from each category is equal. What is the total number of notes that he has?
Options :
Answer : D
Explanation
Let number of notes of each value be z. Then, 10z + 5z + z = 480. If we will solve it then z = 90. Hence option D is the answer.
Q 6 - Average of 5 terms is 10. Average of first two terms is 7 and last two terms is 13. What is value of third item?
Options :
Answer : A
Explanation
Average of 5 terms = 5 × 10 = 50
First two terms = 2 × 7 = 14
Last two terms = 13 × 2 = 26
3rd term = 50 - (14 + 26) = 10
Q 7 - July 28 is my birthday and I usually distribute rasagollas to my friends on that eve. I have a few rasagollas to be distributed. If I keep 2, 3 or 4 in pack, I am left with one Rasagolla. If I keep 5 in a pack, I am left with none. What is the minimum number of rasagollas I have to pack and distribute?
Options :
Answer : A
Explanation
By packing 5 rasagollas in a pack, we would be left with no extra ones.
So, the total number of Rasagollaas is obviously divisible by 5.
This eliminates the option C.
By packing 2,3, or 4 Rasagollas in a pack, we are left with 1 rasogolla
So, (the number of Rasagollas -1) must be divisible by 2,3, and 4
In case of option A, (25 - 1 = 24) is divisible by 2, 3, and 4.
In case of option B, (35 - 1 = 34) is divisible by 2 but is not divisible by 3 and 4. So, this eliminates option B.
In case of option D, (65 - 1 = 64) is divisible by both 2 and 4, but, is not divisible by 3. This eliminates option D also.
So, the only eligible option left with us is 25.
So, option A would be the answer.

Options :
Answer : C
Explanation
Whole work done by Salim in 10 × 4 = 40 days. Whole work done by Milkha in (40 × 100/40) = 100 days. Whole work will be done by Jinson in (13 × 3) = 39 days Therefore, Jinson will complete the work first.
Q 10 - Mr. Das told his son Rinku in a special occasion that, he was of Rinkus current age when Rinku was born. If Mr Das is 36 now, how old was Rinku five years back?
Options :
Answer : B
Explanation
Let Rinkus fathers age be x and the Rinkus age be y.
Then, x y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.Therefore Rinkus present age = 18 years. So, Rinkus age 5 years ago = 13 years.
