Option (a) is correct

Product P sold by company E = 4/7 x (7/100) x (64/100) x 800000 = 20480

Product Q sold by company E = 3/7 x (7/100) x (55/100) x 800000 = 13200

Hence required difference = 20480 – 13200 = 7280

विकल्प (a) सही है।

कंपनी E द्वारा बेचा गया उत्पाद P

= 4/7 × 7/100 × 64/100 × 800000 = 20480

कंपनी E द्वारा बेचा गया उत्पाद Q

= 3/7 × 7/100 × 55/100 × 800000 = 13200

अतः आवश्यक अंतर = 20480 – 13200 = 7280
