Sir can u please suggest me how to solve 13 problem

Basically its is "rule of 72" is simple way to determine how long will ur investment 'double' given in fixed annual rate..but i used 70 in this sum for just convenience thats it. Remember if something increase in fixed annual rate(R) and u required to find a time(N) in certain interest to take the value double. U can use "rule of 72" for to get aprox answer N=72/R
