Answer:
There are a total number of 1656 students in the school.
Step-by-step explanation:
Let's set up this word problem in mathematical terms.
We can call the number of Left Handed Students as X,
and we can call the number of Right Handed Students as Y.
Since there are 276 more right handed pupils than left handed, we have the following equation:
X + 276 = Y -Equation 1
Also, since there are 5/12 ratio of left handed students and 7/12 right handed students, we get:
Total Students = T
(5/12) T = X -Equation 2
(7/12) T = Y -Equation 3
Substituting equations 2 and 3 into equation 1 we get:
[tex]\frac{5}{12} T+276=\frac{7}{12} T[/tex]
Solving for Total number of students (T) we get:
T = 1656
