Answer:
Uma is 11 years 11 months 4 days older
Step-by-step explanation:
Given
Let
x = Uma's age
y = Her brother's
So:
x = 12years 9months 5days
y = 10 months 1 day
Required
How much older is Uma
To do this, we simply calculate the difference (d) in their ages:
This gives:
d = [12 years 9 months 5 days] - [10 months 1 day]
Collect like terms
d = [12 years 9 months - 10 months] + [5 days - 1 day]
d = [11 years 11 months] + 4 days
d = 11 years 11 months 4 days
Answer:
Using the attached formula:
exp = log (total/principal) / n * years
exp = log (10,000 / 7,500) / 12 * 20
exp = log (1.3333333333) / 240
exp = 0.1249387366 / 240
exp = 0.000520578069166667
rate = (10^exp -1) * n
rate = (10^0.000520578069166667 -1) * n
rate = 1.00119939400018 -1 * n
rate = .00119939400018 * 12
rate = 0.014392728
OR rate = 1.4392728 % Compounded Monthly
OR rate = 1.448805264762% Compounded Annually
