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 - 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?
Options :
Answer : A

Q 6 - A is thrice good workman as B and therefore is able to finish the work 60 days less than B. Working together they will finish it in how many days?
Options :

Explanation
Let B takes = x days
A takes = (x-60) days.
Work done by A in 1 day = 3 times work done by B in 1 day
1/(3X-60) = 90A + B = 1/30 + 1/90 = 2/45 = 22 days

Q 9 - Mohasin and Javed work for LPN cement company. Mohasin can do a piece of work in 7 days working for 9 hours each day and Javed alone can do it in 6 days working for 7 hours in each day. How long will both Mohasin and Javed take to complete the job working together 8 2/5 hours a day?
Options :
Answer : A
Explanation
Mohasin can complete the work in (7 × 9) = 63 days Javed can complete the work in (6 × 7) = 42 days
Mohasins one hours work = 1/63 and Javeds one hour work = 1/42
(Mohasin + Javed)s one hour work = (1/63) + (1/42) = 5/126 Therefore, Both Mohasin and Javed can finish the work in 126/5 hours.
Number of days of 8 2/5 hours each = (126 × 5/(5 × 42)) = 3 days
