Step-by-step explanation:

Answer 2

Answer: the interest is calculated on a half-yearly basis is Rs. 60

Step-by-step explanation:

According to the question,

As we know the difference between simple and compound interest on Rs. 6000 for 1 year at 20% per, but interest is calculated on a half-yearly basis.​

By using the formula for 2 years,  CI - SI = P×(R/100)²

Now the interest is calculated on half-yearly

So divide the rate of interest in 2,

So by split the given year in terms of 6 months

so we can use the above equation As

P = 6000

R = $\frac{20}{2}$= 10%

CI - SI = $6000 \times (\frac{10}{100} )^{2}$

       $=6000 \times \frac{10}{100} \times\frac{10}{100}\\= 60$

= Rs 60

So the interest is calculated on a half-yearly basis is Rs. 60.
