   Solution:
   % increase in 2010 = (4250-3400)/3400 * 100 = 25%
   So in 2015 = 120/100 * 4250 = 5100 [5% less so 20% increase]

    View Answer

      Option  E
    Solution:
    A in 2016 = 77 thousand, so in 2017 = 120/100 * 77thousand = 92,400
    B in 2016 = 81 thousand, so in 2017 = 120/100 * 81thousand = 97,200
    Total cars in 2015 = (76+69) = 145,000
    Total cars in 2017 = 92400 + 97200 = 189,600
    So required % = (189600 – 145000)/145000 * 100 = 30.75%
