Question
‘L’ has 28% fewer books than ‘M’. ‘M’ has 30%
more books than ‘N’. By what percent is the number of books with ‘L’ less than that with ‘N’?Solution
ATQ,
Let the number of books with ‘M’ be ‘50x’.
Books with ‘L’ = 0.72 × 50x = 36x
Books with ‘N’ = (50x / 1.3) = 38.46x
Required percentage = {(38.46x – 36x)/38.46x} × 100 ≈ 6.4% or 6%
