Question
‘M’ has 35% fewer marbles than ‘N’. ‘N’ has 40%
more marbles than ‘O’. By how much percent is the number of marbles with ‘M’ less than that with ‘O’?Solution
ATQ,
Let number of marbles with ‘N’ be ‘20x’.
Number of marbles with ‘M’ = 0.65 × 20x = ‘13x’
Number of marbles with ‘O’ = (20x / 1.4) = ‘14.29x’
Required percentage = {(14.29x – 13x)/14.29x} × 100 ≈ 9.03% or 9%
