Answer & Explanation Difference= 5 x (73 – 27) /100 = 2.3 lakh tones India= 50 x (18/100) x (32/100) = 2.88 lakh tones Japan = 50 x (20/100) x (78/100) = 7.8 lakh tones China= 50 x (22/100) x (70/100) = 7.7 lakh tones Bangladesh= 50 x (8/100) x (20/100) = 0.8 lakh tones Pakistan= 50 x (9/100) x (66/100) = 2.97 lakh tones Indonesia= 50 x (10/100) x (73/100) = 3,65 lakh tones Sri Lanka= 50 x (13/100) x (60/100) = 3.9 lakh tones So Avrg = (2.88 + 7.8 + 7.7 + 0.8 + 2.97 + 3.65 + 3.9)/7 = 4.24 lakh tones Production by scientific method in Japan= 7.8 lakh tones Required ratio= 1.53 : 7.8 = 51 : 260 Production in India by scientific method= 50 x (18/100) x (32/100) = 2.88 lakh tones According to question, 2.88 X x = 2.6 x = 2.6/2.88 = 0.9 times Production of wheat in India by Scientific method= 50 x (18/100) x (32/100) = 2.88 lakh tones Production in Pakistan by Conventional method=50 x (9/100) x (34/100) = 1.53 lakh tones According to question = 2.88/1.53 = 1.88 times
