Rahul purchased pencils from two different shops A and B in the ratio 3:7 respectively. Find the number of pencils he purchased from shop A.
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 Number of pencils he purchased from shop A = 80 × (3/10) = 24
