it is right answer

Answer 2

Answer :

• Compound interest = ₹996
• Amount = ₹7,396

Explanation :

Given :

• Principal = ₹6,400
• Time = 2 years.
• Rate = 7½% p. a. (per annum)

Calculate the amount and compound interest.

Using amount formula :

$\sf \longrightarrow amount = p \bigg(1 + \dfrac{r}{100} { \bigg)}^{n}$

Where,

• p(principal) = ₹6,400
• n(time) = 2 years.
• r(rate) = $\sf \dfrac{15}{2}\%$

From the given values :

$\sf \longrightarrow amount = 6400 \bigg(1 + \dfrac{15}{200} { \bigg)}^{2}$

$\sf \to 6400 \bigg(1 + \frac{3}{40} \bigg)^{2}$

$\sf \to 6400 \bigg( \frac{43}{40} \bigg)^{2}$

$\sf \to 6400 \bigg( \frac{43}{40} \times \frac{43}{40} \bigg)$

$\sf \to 6400 \times \frac{43}{40} \times \frac{43}{40}$

$\sf \to 4 \times 43 \times 43$

$\sf \to 7396$

$\therefore { \underline{\sf{The \: amount \: i s \: ₹7396}}}$

Calculate the compound interest :

We know that,

➛ C. I. = Amount - principal

➛ C. I. = ₹7,396 - ₹6,400

➛ C. I. = ₹996

Hence, the compound interest is ₹996
