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
You have the formula. Put in the numbers and solve for r.
The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B
