      Solution

      Total apples sold by ‘P’ = 1080/1.20 = 900 Green apples sold by ‘P’ = (900 – 100)/2 = 400 Red apples sold by ‘P’ = 900 – 400 = 500 Green apples sold by ‘Q’ = 3/2 × 400 = 600 Red apples sold by ‘Q’ = 1080 – 600 = 480 Red apples sold by ‘R’ = 0.80 × 480 = 384 Green apples sold by ‘R’ = 384/1.50 = 256 Total apples sold by ‘R’ = 256 + 384 = 640 Total apples sold by ‘S’ = 680 × 2 – 640 = 720 Green apples sold by ‘S’ = 5/12 × 720 = 300 Red apples sold by ‘S’ = 7/12 × 720 = 420 Number of Red apples sold by ‘P’ and ‘Q’ together = 500 + 480 = 980 Number of Green apples sold by ‘R’ and ‘S’ together = 256 + 300 = 556 Required difference = 980 – 556 = 424
