Question
In a garage, 80% of the vehicles are two-wheelers and
the remaining are four-wheelers. Find the ratio of the number of wheels of two-wheelers to that of four-wheelers.Solution
ATQ, Let the total number of vehicles be x.
Number of two-wheelers = 0.80x
Number of four-wheelers = 0.20x
According to the question,
(2 × 0.80x) / (4 × 0.20x) = 1.6x / 0.8x = 2:1
