Question

in a classroom there are 'n' number of rows.in each row there are 6 benches. each bench can accommodate 2 children. if all benches are occupied and still two children are standing,find the number of children in the classroom ​.

Answer 1

Answer:

Total number of children in the classroom are (10n + 2).

Explanation:

Step-by-step explanation: There are n rows in a class room.

Each row has 5 benches.

Total number of benches = Number of rows x Number of children in each row

= 5n

Each bench can accommodate 2 children then number of children accommodated on all benches = Total benches x number of children in each bench

= 5n x 2

= 10n

Even after this number of children standing in the class = 2

Therefore, total number of children in the class = (10n + 2)
