Question

Kelvin, Teddy and Jim scored a total of 83 points during a competition. Teddy scored 13 points less than Kelvin. Teddy scored 3 times as many points as Jim. How many points did each of the boys score?

Answer 1

According to question,

let points scored by Teddy be x

so,

Kelvin = x + 13

Jim = x/3

x + x + 13 + (3x) = 83

⇒ 5x + 13 = 83

⇒ 5x = 70

⇒ x = 14

then,

Kelvin = x + 13 = 27

Jim = 42
