Question

At how much rate a sum becomes doubles in 16 yr?​

Answer 1

Answer:

At 6.25 % rate a sum becomes doubles in 16 years.

Step-by-step explanation:

Simple Interest = $\frac{(PRT)}{100}$

Sum doubles in 16 years means

=> Principal amount + simple interest of 16 years = 2 X principal amount

                                   $\frac{P+16PR}{100} =2P\\ \\ \frac{16PR}{100} =P\\ \\ R=\frac{100}{16} \\ \\ R=6.25$
