Question

The students of a class arranged a picnic. Each student contribute as many rupees as the number of students in the class . If the total contribution is $Rs. 1156$, find the strength of the class.

Answer 1

lets assume that the strenght of the class is S
now
S x S = 1156
S² = 1156
S=√1156
S=34

So the strengh of the class is 34

Answer 2

Answer:

let no. of students in the class be X

x×x = 1156= X square =1156

x=√1156=√2×2×17×17

2×17=34

no. of students of the class =34
