Explanation:
1). Reqd % =(285/540) x100 ≈53
2). Reqd average = (190 + 285+315 + 240+265) / 5 =1295 /5 =259
3). For the sake of convenience we consider only the first two digits of the numbers. From the observation of the table we go only for NMDC and Hindal.co
Then, NMDC -->( 30 + 54 + 32 + 10 + 5) = 131 Hindalco --> (15 + 46 + 48 + 35 + 20) = 164 Thus, Hindal.co produced the maximum quantity of mining items.
4). Reqd ratio = 600 : 255 = 40 : 17
5). Reqd difference = 350 - 140 = 210
6). = (2270+2420+3840+5240+7200) / 5 - (2750+3320+4260+4850+5450) / 5
=20970/5 – 20630/5
=4194 - 4126
=68
7). Reqd ratio =(4260 + 4840) /( 6100+7200) = 9100/13300
= 13:19
8). Reqd % = (18285+20970) / (20460+22065 ) x100
39255 / 42525 x100 ≈ 92%
9). Reqd total = (1250 + 2750 + 1930 + 2270 + 3050 + 2420 + 3320 + 2550 + 2420 + 2525) = 24485
10). Reqd % (4860+5240)-(3320+2550) / (4860+5240) x 100
= (10100-5870) / (10100) x100 4230/10100 x100
= 41.88%
