In a building with various offices on 12 floors there are two lifts. Lift 1 halts at even numbered floors and Lift 2 at odd numbered. A, B, C and D have their offices on 2, 8, 7 and 11 floors respectively. The office reaching time for A and C is 9:10 am while for B and D is 9:15 am and 9:20 am respectively. The attendance will be marked on the floor office. The lift takes 30 seconds to cross from one floor to another and halts on the selected floor for 30 seconds. The employees have to complete 8 hours and 30 minutes per day and are allowed to be late in the morning up to a maximum of 30 minutes which has to be compensated for in the evening. They have to enter the building from Ground i.e. ‘0’ floor and it is not necessary that the lift is always available.
Question for LRDI For IIFT 2019
Try yourself:D steps into Lift 1 by mistake with in it at 9:00 am at the ground floor and C is in Lift 2 at ground floor at the same time and realises only when the lift has started. Then approximately at what time will D reach office, if Lift 2 halts for additional 30 seconds after D boards it ?
Explanation
C travels for 7 floors on lift 2. It takes 3.5 minutes. Further it takes another .5 minutes at the 7th floor.Total of 4 minutes.
It travels another 3.5 minutes to the ground floor and spends 0.5 minutes halting at ground floor. Total of 8 minutes.
Now it travels for 5.5 minutes to the 11th floor. The question mentions that it halts for an extra 0.5 minutes. Therefore it takes 6 minutes. Total of 14 minutes.
Answer therefore is 9:14.
Question for LRDI For IIFT 2019
Try yourself:If A reaches the building at 9:08 am and Lift 1 is at the 6th floor with only B in it, at what time can at the earliest leave from office on that given day ?
Explanation
The lift is at the 6th floor. It takes 1 minute to reach 8 th floor. Further it stops for 30 seconds here.
It climbs down 8 floors. It takes 4 minutes for the same. It takes 30 seconds to halt at ground floor. Now it travels 2 floors to second floor in 1 minute. Totally it takes 7 minutes.
Therefore B reaches office at 9:15, which is his office start time. He can therefore leave office is 8 hours 30 minutes which is 5:45

In an organisation with three departments i.e. Marketing, Finance and HR, it was decided to shuffle the 70 employees between departments. To make optimum use of resources, the management assesses their capability based on their qualification. 3 employees can work in every department. 7 employees can work in Finance and Marketing only. 10 can work only in HR while the number of employees only in Marketing is double of that in only Finance. Employees in only Finance cannot be less than 10 while employees in Finance and HR only are three times of two less than that of Marketing and HR only. The organisation has employees with all possible combinations of their capabilities.
Question for LRDI For IIFT 2019
Try yourself:How many employees are capable to work in Marketing and HR only?
Explanation
We know that x + x/2 + k + 3 + 3k - 6 + 10 + 7 = 70
3x /2 + 4k = 56
The solutions possible are x = 24, k = 5 and x = 32 and k = 2. But if k = 2 then, only finance and hr would have 0. This is not possible as the question states that there exists employees in all
possible combinations.
The number of employees in only marketing and HR is 5.
