Answer 2

Your Answer :-
As we know that Simple Interest = Principal amount × rate of interest (per year) × time (year)

Then as provided
Principal amount = ₹6400
Rate of interest per year = 6%
or $\frac{6}{100}$
Time = 2 years

Now by applying equation

Simple Interest= 6400 × $\frac{6}{100}$ × 2

= 64 × 6 × 2

= ₹768

Now as amount = SI + Principal amount
= 6400 + 768
= ₹7168
