= (58248 × 28)/100 + (63309 × 21)/100 + (70316 × 27)/100 + (69294× 23)/100 + (59216 × 20)/100
= 16309.44 + 13294.89 +18985.32 + 15937.62 + 11843.2
= 76370.47
Answer is: d)
2).Number of candidates passed from Nagaland in 2010, 2011 and 2012
= (34145 × 12)/100 + (17264 × 10)/100 + (24800× 15)/100
= 4097.4 + 1726.4 + 3720
Average = 9543.8/3 = 3181.26
Number of candidates passed from Haryana in 2013, 2014 and 2015
= (71253 × 19)/100 + (69632 × 16)/100 + (64178× 21)/100
= 13538.07 + 11141.12 + 13477.38
= 38156.57
