I'll use my own formula (similar to yours tho)
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years
so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so
divide both sides by P
simplify
take the ln of both sides
divide both sides by 4ln(1.03)
use calculator
5.86244=t

Answer:
The correct option is 4.
Step-by-step explanation:
It is given that 10 men and 12 women will be seated in a row of 22 chairs.
Total possible ways to arrange n terms is n!.
Similarly,
Total possible ways to place 22 people on 22 chairs = 22!
It is given that all men will be seated side by side in 10 consecutive positions.
Total possible ways to place 10 people on 10 chairs = 10!
Let 10 men = 1 unit because all men will be seated side by side in 10 consecutive positions. 12 women = 12 units because women can any where.
Total number of units = 12 + 1 = 13.
Total possible ways to place 13 units = 13!
Total possible ways to place 10 men and 12 women, when all men will be seated side by side in 10 consecutive positions is
The probability that all men will be seated side by side in 10 consecutive positions
Therefore the correct option is 4.
