Answer 2

In what time will rs 3600 amount to rs 4410 at 9% per annum simple intrest

Principal = ₹3600

Amount = ₹4410

Interest = Amount - Principal

= ₹4410 - ₹3600

= ₹810

Now,

$\mathtt{t = \frac{i \times 100}{p \times r} } \\ \\ \implies\mathtt{ \frac{810 \times 100}{3600 \times 9} } \\ \\ \implies\mathtt{2 \frac{3}{6} } \\ \\ \implies\mathtt{2 \frac{1}{2} \: years \: ans}$
