Class alphabet

All 29 pupils in the class are written in a class by alphabet. The number of pupils enrolled before Paul is three times higher than the number of pupils behind him. Calculate how many pupils are enrolled after Paul.

Correct result:

n =  7

Solution:


3n + 1 + n = 29

3•n + 1 + n = 29

4n = 28

n = 7

Calculated by our simple equation calculator.
