The number of pencils that Manish have is how much percent less than that of Lakshay?
Let number of pencils purchased by Aman and Rahul be 3x and 5x respectively. Number of pencils purchased by Lakshay = 60 Number of pencils purchased by Manish = 60 – 20 = 40 Number of pencils purchased by Gagan = (70/100) × 60 = 42 Number of pencils purchased by Aman, => 3x = (120/100) × 40 => x = 16 Therefore, number of pencils purchased by Aman = 3x = 48 And number of pencils purchased by Rahul = 5x = 80 Required % = [(60 – 40)/60] × 100 = 33.33%
