Answer 1

Answer:

the total interest after 3 years is ₹5670/-

Step-by-step explanation:

total money borrowed = ₹12000

out of those Rs.4000 is of 18% interest rate and remaining 12000 - 4000 = 8000 is of 15% interest rate.

total interest = p*r*t/100

Answer 2

Answer:

=> Total interest is Rs. 5760.

Step-by-step explanation:

As per the data given,

We have to find the total interest,

Given that:-

Borrowed money by Radhika = $Rs. 12000$

(i) Principal = $Rs. 4000$

Time = $3$ years

Rate of interest = $18\%p.a$

As we know that,

Simple Interest ( S.I )

$=> \frac{P\times R\times T}{100}$

Plug the values in the formula, we get

$=> \frac{4000\times 18\times 3}{100}$

$=> 2160$

(ii) Principal

$=12000-8000=Rs.4000$

Time = $3$ years

Rate of interest = $15\%p.a$

Simple Interest ( S.I )

$=> \frac{P\times R\times T}{100}$

Plug the values in the formula, we get

$=> \frac{8000\times 15\times 3}{100}$

$=> 3600$

For calculating, total interest

$=> 2160+3600\\=>Rs.5760$

Hence, after 3 years the total interest is Rs. 5760.
