Answer 1

Answer:

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

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

heir total scored is 76

=>lets form an equation

=> k+r+b = 76

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

=> 3k +10 =76

=>3k = 76-10

=>3k =66

=>k =22

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

kaku scored 22marks

r = k +3 b = k+7

= 22+3 = 22+7

=25 marks = 29 marks
