Find the marks obtained

by each.

Calculation:

10 marks => Class test conducted.

Given marks in square => 45

Marks obtained by Raman => 4

10 / 45 × 4 => 10

Answer 2

Given :-

Jitesh and Raman are two friends. In a maths class test of 10 marks, they have got marks in such a way that difference of the square of their marks is 45. the square of marks obtained by Raman is four times the marks obtained by Jitesh. it is given that jitesh has got more marks than Raman . find the marks obtained by each.

to find:-

Marks obtained by Raman

Marks obtained by jitesh

direction

no. of marks = 10

hence , 10 marks = Class test conducted.

Given marks in square = 45

marks obtained by Raman = 4

$marks \: obtained \: by \: raman \\ = \frac{10}{45} \\ = 0.222$

$marks \: obtained \: by \: jitesh \\ = \frac{10}{45} \times 4 \\ = 10$
