In a public library, the following observations were recorded by the librarian in a particular week.
$\begin{array}{ccccccc}& & & & & & \\ \text{Days}& \text{Mon}& \text{Tue}& \text{Wed}& \text{Thur}& \text{Fri}& \text{Sat}\\ \text{Newspaper readers}& 400& 600& 350& 550& 500& 350\\ \text{Magazine readers}& 150& 100& 200& 300& 250& 200\end{array}$
On which day, the number of readers in the library was maximum?

Answer 1

Total number of both readers on different days are
$\begin{array}{cc}& \\ \text{Day}& \text{Readers}\\ \text{Mon}& 400+150=550\\ \text{Tue}& 600+100=700\\ \text{Wed}& 350+200=550\\ \text{Thur}& 550+300=850\\ \text{Fri}& 500+250=750\\ \text{Sat}& 350+200=550\end{array}$
Hence, it is clear that the number of readers was maximum on Thursday.
