Answer:
- 4, 7
Step-by-step explanation:
Let the required number be x.
Therefore, according to the given condition:
<u>Answer-</u>
The total interest after 3 years is Rs.5760 .
<u>Solution-</u>
Total money borrowed = Rs.12000
Out of those Rs.4000 is of 18% interest rate and remaining 12000-4000=8000 is of 15% interest rate.
Where,
P₁ = principal amount = Rs.4000
P₂ = principal amount = Rs.8000
r₁ = rate of interest of P₁ = 18%
r₂ = rate of interest of P₂ = 15%
t = time period = 3 years
