Answer 1

Answer:

Let the time be x

Convert rate of interest in improper fraction =

=> 42 = 2%

Now, rate is 9/2%.

<= 3x9xx 2 = 6.75

300×9xx

100×2

21.2 => = 6.75 2

=> x=

6.75x2

=> x= 13.5 21

=> x = 0.64

We will multiply it by 12 to get it into months.

0.64X 12= 7.68 months

7.68 = 9 months approx.
