Study the following bar graph and answer the question that follows.
In which of the following pairs of years, the average export of diamonds was closest to ₹12 crores?
Answer & explanation
Correct answer: option 2
Lets solve one by one for each option.
1. 2010 and 2011
Average export of diamonds in 2010 and 2011 = \(\frac{9.8+10.9 }{2 }\)
= \(\frac{ 20.7 }{2 }\)
= 10.35
2. 2013 and 2014
Average export of diamonds in 2013 and 2014 = \(\frac{11.5+12.4 }{2 }\)
= \(\frac{ 23.9 }{2 }\)
= 11.95
= 12 ( approx )
3. 2011 and 2012
Average export of diamonds in 2011 and 2012 = \(\frac{10.9 + 11.8 }{2 }\)
= \(\frac{ 22.7 }{2 }\)
= 11.35
4. 2012 and 2013
Average export of diamonds in 2012 and 2013 = \(\frac{11.8+11.5 }{2 }\)
= \(\frac{ 23.3 }{2 }\)
= 11.65
So , Average export of diamonds in 2013 and 2014 is nearly equals to Rs. 12 crore.
