Question

Average score of rahul, manish and suresh is 63. rahul's score is 15 less than ajay and 10 more than manish. if ajay scored 30 marks more than the aver ge scores of rahul, manish and suresh, then what is the sum of manish's and suresh's scores?

Answer 1

Avg Score - 63
Let score of Rahul be x
                    Ajay be x+15
                    Manish be x-10
x+15 = 63 + 30 
x = 78  = Rahul's score
x-10 = 68 = Manish's score

Let score of suresh be y

y + 78 + 68 = 63 * 3
y = 43 = Suresh's score

Sum of Manish's score and Suresh's score is 43 + 68 = 111

Ans : 111
