A man wants to purchase a car and for that, he checks the rating of the car on the internet. He finds the ratings of 9/10 for comfort and 8/10 for resale value. Based on his requirements, he gives a weightage of 55% to comfort and 45% to resale value. Calculate the final rating of the car
Show answer & explanation
Correct answer: A
Explanation
The Correct answer is option 1 i.e. .
His comfort ratings = 9/10
Comfort weightage = 55%
resale value ratings = 8/10
resale value weightage = 45%
Average ratings = [(comfort ratings × Comfort weightage) + (resale value ratings × resale value weightage)]/(Comfort weightage + resale value weightage
= [(9/10 × 55%) + (8/10 × 45%)]/(55% + 45%)
=
= 855/1000
=
