Answer : 5 Explanation : Production of Punjab is maximum = 105000 tonnes 3. Answer : 3 Explanation : Production of Wheat in Punjab = 40000 tones Production of Maize in Odisha = 10000 tones Required % = (40000 - 10000)/100 = 300% 4. Answer : 4 Explanation : The ratio of prodution of Rice in Bihar to the production of Wheat in Haryana = 25000 tonnes : 25000 tonnes = 1 : 1 5. Answer : 1 Explanation : Income of MP from export of 40% of Rice at the rate of Rs.30 per kg = Rs.39crore Income of UP from export of 30% of Rice at the rate of Rs.32 per kg = Rs.28.8 crore Required ratio = 39 : 28.8 = 390 : 288 = 65 : 48

1. Answer : 1 Explanation : Quantity of Guava at Shop A = 1200×10100 = 120 kg Quantity of Guava at Shop B = 1000×16100= 160 kg Therefore, Required difference = 160 - 120 = 40 kg 2. Answer : 2 Explanation : Cost of Mango at Shop A = 30×1200×24100= Rs. 8640 Cost of Apple = 40×1200×16100 = Rs. 7680 Cost of Orange = 20×1200×20100 = Rs.4800 Therefore, Required Ratio = 8640 : 6780 : 4800 = 9 : 8 : 5 3. Answer : 3 Explanation : Quantity of Mango at Shop B = 1000×24100 = 240 kg Quantity of Mango at Shop A =1200×24100 = 288 kg Therefore, Req % = 288×100240 = 120% of the quantity of Mango at Shop A 4. Answer : 4 Explanation : Cost of total fruits at Shop A = Cost of Mango + Cost of Apple + Cost of Guava + Cost of orange + Cost of other fruits =1200×24100×30 + 1200×16100×40 + 1200×10100×18 + 1200×20100×20 + 1200×30100×15 = Rs. 28680 Cost of Total Fruits at Shop B =1000×24100×30 + 1000×14100×40 + 1000×16100×18 + 1000×20100×20 + 1000×26100×15 = 7200 + 5600 + 2880 + 4000 + 3900 = Rs. 23580 Therefore, Req.difference = 28680 - 23580 = Rs.5100 5. Answer : 5 Explanation: Quantity of Orange at Shop A = 1200×20100 = 240 kg Quantity of Apple at Shop B =1000×14100 = 140 kg Therefore, Req % = 240×100140 = 171.42% more than the quantity of Apple at Shop B.
