Answer:
r=7
Step-by-step explanation:
74000=28000(1+r/12)^12(14)
divide 74000 by 28000, and cancel out 28000.
1.00580=1+r/12
(100) .06962=r
r = 6.96198
the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7
r=7
Given parameters:
Fraction given to charity = 
Fraction given to wife = 
Unknown:
Fraction given to son and daughter =?
Solution:
Let the total property = x
Fraction given to charity = 
Fraction given to wife =
The remaining was given to son and daughter = F
So;
Total property = fraction given to charity + fraction given to wife + fraction given to son and daughter
x = 
F = x - (
)
F = 0
The son and daughter will not inherit anything
50% of 40 is 20, and 40% of 50 is 20, neither one is greater, they're equal
6 + 2 < 9 + 3...u r correct
