Answer 2

Step-by-step explanation:

$\huge\mathbb\green{QUESTION:-}$

The students of class 8 of a school donated rs 2401 in all,for prime minister's national relief fund. each student as many rupees as the number of students in the class. find the number of students in the class.

$\huge\mathbb\red{ANSWER:- }$

$\huge\mathfrak\orange{SOLUTION:-}$

$Let  \: x  \: be \: the \: number \: of students \: in \: the \: class.$

$Thus, \: amount \: deposited \: by \: a \: student \: is \: Rs.  \: x$

$If, \: each \: student \: deposits \: Rs.  \: x  \: for \: Prime \: Ministers \: National \: Relief \\ Fund \: in \: a \: class \: of  \: x  \: students, \: then \: the \: total \: sum \: donated \: by \: the$

$class  \: = \: x {}^{2}$

$Now,$

$x {}^{2} =2401$

$⇒ \: x \: = \: \sqrt{2401}$

$= \sqrt{7×7×7×7}$

$=7×7$

$=49$

$hence \: the \: answer \: is \: 49.$
