basic mathematics mcqs with solution
Solution:
This looks as percent problem – but if seen carefully it is interest calculation problem
We are given following information;
Increase rate = 5%
Present Population = 64000
Time Duration = 3 Years
Population after 3 years =?
To use the interest formula;
We assume here that;
A= Population after 3 years=?
P= Present Population=64000
R= Rate of increase=5
T= 3 (years time)=3
So, the population after three years will be 74088
