T = 81/3 years

I HOPE THIS ANSWER WILL BE HELPFUL

Answer 2

Answer:

8.33 or 8 years and 4 months

Step-by-step explanation:

SI = PTR/100

In the first case,

SI = 4000 × T × 3 / 100

120 T

In the second case,

SI = 5000 × 5 × 4 / 100

= 1000

So the rime taken will be,

120T = 1000

T = 25/3

T = 8.33 or 8 years and 4 months
