Question

Students of a school have been divided into two groups in the ratio of $6:11$ If the first group has $870$ students$.$ How many students are there in all in the school$?$

Answer 1

Step $1:$ To find all the students in the school

Given the number of students in first group $=870$

Ratio of students in two group $=$$6:11$

Sum of the terms of the ratio $=6+11$

$=17$

Step $2:$ Now find the total number of students using the concept of ratio

Number of students in first group $=\frac{6}{17}\times$Total number of students in the school

Total number of students in the school $=\frac{870\times 17}{6}$

$=145\times 17$

$=2465$

Hence, the number of students in the school are $2,465$
