Answer:
Solution
Let the number of students in the class be xx
Therefore, contribution by each student is Rsxx
According to question, x×x=1156x×x=1156
x2=1156⇒x=√1156⇒x=√342⇒x=34x2=1156⇒x=1156⇒x=342⇒x=34
The strength of class is 3434 students.
Answer:
let the no. of students be x
so now if they contribute as much as the no. of students,
total amt=x squared
1156=x squared
34=x
(because square root of 1156 is 34)
therefore no. of students are 34 and each student paid rs. 34
