Question
In a row of students, Nishtha is 7th from left
and Deeksha is 14th from right and the number of students sitting between them is one-fourth the total number of students. Find the total number of students in the row?Solution
Let total number of students = x
Then, number of students between
Nishtha and Deeksha =x/4
x - (7 +14) =x/4
x - 21= x/4
x- x/4=21
(3x)/4=21
= 28 x = 28
