Question 6 Answer
Given
The population of Hyderabad was 6809000 in the year 2011.
it was increases by 4.7 % annum.
we need to calculate the population of after 4 years with given rate of interest.
we will use the compounding formula
Z=A+(1 +r/100) t
where Z is population at the end of duration
A is present population
t is tme perior
r is rate of interest
we we know that 4.7 % = 0.047
putting the values
Z=6809000+(1+4.7/100)⁴
Z =6809000 (1.047) ⁴
Z=6809000 ×1.2016741717
Z =8182199
does does population at the end of 2015 will be 8182199......
Question 7 Answer
For 1st year
P=10000, R = 8.7, T=1
interest= PRT /100
=(10,000×8.7 ×1 )/100
=850
amount = interest+principal = 10000 +850
= ₹10850
for for second year principal will be amount of previous year ( since interest is compound) .
P= 10850, R = 8.5%, T = 3 months = 3/12 years = 0.25 years
interest = PRT/100
=(10850 ×8.5%×0.25 )/100
₹230.5625
total interest= 850 + 230.5625 =₹1080.5625
★ compound interest paid after 1 year and 3 months is ₹1080.5625 .........
