Question

There are twenty people working in an office. The first group of five works between $8.00$ A.M. and $2.00$ P.M. The second group of ten works between $10.00$ A.M. and $4.00$ P.M. And the third group of five works between $12$ noon and $6.00$ P.M. There are three computers in the office which all the employees frequently use. During which of the following hours the computers are likely to be used most ?

• A. $10.00$ A.M. $-12$ noon
• B. $12$ noon $-2.00$ P.M.
• C. $1.00$ P.M. $-3.00$ P.M.
• D. $2.00$ P.M. $-4.00$ P.M.

Answer 1

The correct option is B $12$ noon $-2.00$ P.M.

From the given timings of the three groups, the time of three groups that coincide with each other is from $12$ noon to $2:00$ PM which means all the employees will be present at this time and hence, the computers will be used most at this time.
