Answer 1

Correct Answer - Option 3 : 1

Given:

The following table shows the number of families and the total quantity of rice (in kilograms) consumed by them in the six villages of a district in the years 2016 and 2017.

Calculation:

The total quantity of rice (in kilograms) consumed by them in the six villages of a district in the years 2016

⇒ A = 5400/480 = 10.5 kg

⇒ B = 6100/630 = 9.68 kg

⇒ C = 7900/950 = 8.31 kg

⇒ D = 4325/540 = 8 kg 

⇒ E = 6600/750 = 8.8 kg 

⇒ F = 1200/150 = 8 kg

The total quantity of rice (in kilograms) consumed by them in the six villages of a district in the years 2017

⇒ A = 5200/490 = 10.61 kg

⇒ B = 6150/640 = 9.60 kg

⇒ C = 8100/900 = 9 kg

⇒ D = 4300/520 = 8.26 kg 

⇒ E = 6800/760 = 8.94 kg 

⇒ F = 1150/140 = 8.21 kg

∴ Only village B has reduced its consumption from 9.68 kg to 9.6 kg.
