Given: Number of passengers using Dubai Metro was 10,000 in 2009. The passengers increase at rate of 15% p.a.
To find: Number of passengers travelling in 2011
Solution:
Person travelling in 2009(P)= 10,000
Rate of increase=15%
Time= 2 years
Therefore, increase in number of passengers(S.I)= (P* Rate* Time)/100
= (10,000*15*2)/100
=3,000
Total number of passengers travelling in 2011= Number of people travelling before+
number of person increased
=10,000+3,000
= 13,000
Therefore the number of people travelling in 2011 will be 13,000.
