total marks obtained by all three is 76.
Find the marks obtained by Raman.​

Answer 1

Answer:

Kaku scored 22marks

Raman scored 25 marks.

Bakshi scored 29marks.

Explanation:

let Kaku be k; Baksi be b; Raman be r

Kaku scored 7 marks less than Bakshi

Raman scored 3 marks more than Kaku

b = k +7

r= k+3

-------------------

Their total scored is 76

let's form an equation

= k+r+b = 76

= k+[k+3]+[k+7] =76

= 3k +10 =76

= 3k = 76-10

= 3k =66

= k =22

-------------------

This, Kaku scored 22marks

r = k +3 b = k+7

= 22+3 = 22+7

=25 marks = 29 marks

Raman scored 25 marks.

Bakshi scored 29marks.
