Question

The students of a class aranged a picni. Each student contributed as many as the number of the students in the class. If the total contribution is Rs.1156, find the strength of the class.​

Answer 1

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 2

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
