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.
