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?
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?
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 - In between two file ends in the rack are six paper weights. If you decide to arrange the six paper weights in every possible combination and moved just one paper weight every minute, how long would it take to you?
Clearly, we can get the answer by taking the factorial.
= 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720.
So total time taken = 720 minutes = 12 hours.
Q 4 - A can do ¼ of a work in 10 days, B can do 40% of work in 40 days and C can do 1/3 of work in 13 days. Who will complete the work first?
Whole work will be done by A in 10 × 4 = 40 days. Whole work will be done by B in (40 × 100/40) = 100 days. Whole work will be done by C in (13 × 3) = 39 days. Therefore, C will complete the work first.
Q 5 - In a cards game which hold regularly on roof top each night, Saroj holds 13 cards of four suits. Among them 6 hold cards are of red and 7 hold cards are of black colour.

Q 6 - A canteen requires 17 dozen eggs per day. How many eggs will it require for 13 weeks?
Daily requirement = 17 × 12 (one dozen = 12 units)
Required in one week = 17 × 12 × 7
Required in 13 weeks = 17 × 12 × 7 × 13 = 18564

When traffic is more normally the stoppages for Maharathi will be more but when it travels in early morning the stoppages are absolutely less. Excluding stoppages, the speed of Mahrathi is 54 kmph and including stoppages, it is 45 kmph. For how many time will Maharathi bus stops per hour?
Maharathi bus will stop for ten minutes, so, option c is correct.
Q 9 - Mehendi plucked 175 flowers and Pulak plucked 225 flowers. If flowers are to be placed in 5 threads. Then each thread will contain how many flowers in it?
175 + 225 = 400. 400/5 = 80.
Q 10 - Mr. Das told his son Rinku in a special occasion that, he was of Rinku’s current age when Rinku was born. If Mr Das is 36 now, how old was Rinku five years back?
Let Rinku’s father’s age be x and the Rinku’s age be y.
Then, x – y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.Therefore Rinku’s present age = 18 years. So, Rinku’’s age 5 years ago = 13 years.
