The answer is, 58.5
Direction (6-10) :
6) Answer: a)
The total production of rice in the year 2012 and 2014 together
= > 528 + 756 = 1284
The total production of rice in the year 2015 and 2017 together
= > 694 + 806 = 1500
Required difference = 1500 – 1284 = 216
7) Answer: d)
Production of A2 category rice in the year 2013
= > 612*(4/9) = 272
Production of A3 category rice in the year 2016
= > 720*(3/9) = 240
Required ratio = 272: 240 = 17: 15
8) Answer: b)
The average production of rice in all the given years together
= > (528 + 612 + 756 + 694 + 720 + 806)/6
= > 4116/6 = 686
9) Answer: a)
Total production of rice in the year 2014 = 756
Total production of rice in the year 2017 = 806
Required % = (756/806)*100 = 94 %
10) Answer: c)
The average production of rice in the year 2012, 2014 and 2016 together
