Question

Q 45. If the ratio of the score of Andy, Kevin, and Paul in a test is 2:5:9. If their total score is 144, then find Kevin's son
Ops: A C60
B. 081
D. 18​

Answer 1

Answer:

Given, ratio of scores = 2:5:9

Let, Scores of Andy , Kevin and Paul be 2x, 5x, 9x respectively.

BTP,

2x+ 5x + 9x = 144

=> 16x = 144

=> x = 9

Thus, Kevin's score = 5x = 5*9= 45

         Andy's score = 2x = 2* 9 = 18

         Paul's score = 9x = 9*9 = 81

Answer 2

Answer:

Kelvin's score is 45.

Step-by-step explanation:

The ratio of scores of Andy, Kevin, and Paul = 2:5:9

Lets assume the common factor of the ratio is x.

• Score of them: Andy's score= 2x

                         Kevin's score = 5x

                         Paul's score = 9x

        Total score = 16x

• According to the question, 16x = 144

                                             x = 9

           So, Kevin's score = 5x = 5 X 9 = 45
