Answer 2

Here, Amount = 1280Rs. and Principal = 1200Rs.

Then, Simple Interest = 1280-1200 = 80Rs.

Also, Given that : Time = 1 year 2 months = 14 Months

Now, According to the question :

$80 = \frac{1200 \times 14 \times r}{100 \times 12} \\ \\ = > r = \frac{80 \times 100 \times 12}{1200 \times 14} \\ \\ = > r = 5 \frac{5}{7}$%
