Answer = ₹2475 . [Solution below]

Step-by-step explanation:

Question :-

Find the interest : ₹9000 at 5% per annum in 5.5 years.

[ Here, you might be wondering that how it became 5.5 years. I converted the fraction into decimal. Let me show you how it's done :

$= > 5 \frac{1}{2} years$

$= > \frac{11}{2} years$

$= > 5.5 \: years \: \: \: \: \: \: \: \: \: \: \: \: \: \: (11 \div 2 = 5.5)$

Now, I hope it's clear to you ]

Solution :-

Here,

Principal = ₹9000

Time = 5.5 years

Rate = 5% p. a.

We know,

$i \: = \: \frac{p \: \times \: r \: \times \: t}{100}$

$i \: = \: \frac{9000 \times 5 \times 5.5}{100}$

$i \: = 90 \times 5 \times 5.5$

Interest = ₹2475
