Question

Answer 1

The Luck's score is 260 marks.

Given - Ratio and total score

Find - Luck's score

Solution - Let the score of Lily and Luck be 11x and 13x. Now, relating the given values with total score, to find the value of x.

Representing the given information in equation form -

11x + 13x = 480

Taking sum of values on Left Hand Side

24x = 480 Shifting 24 to Right Hand Side of equation

$x = \frac{480}{24}$

Performing Division to find the value of x

x = 20

Now, finding Luck's score.

Score = $13 \times 20$

Luck's score = 260

Hence, Luck scored 260 marks.
