Answer : ₹ 15600

━━━━━━━━━━━━━━━━━━━━━━━━━

Given:

A sum at simple interest of 4%per ANNUM to 3120 in 5 years

━━━━━━━━━━━━━━━━━━━━━━━━━

To find:

What is the sum?

━━━━━━━━━━━━━━━━━━━━━━━━━

Solution:

Applying interest FORMULA,

━━━━━━━━━━━━━━━━━━━━━━━━━

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\:I \: = \: \frac{P \: \times \: R \: \times \: T}{100} }} }\\ \\\end{gathered}\end{gathered}$

Principal = ?
Rate = 4%
Time = 5 years
I = ₹3120

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: 3120 \: = \: \frac{P \: \times 4 \: \times \: 5}{100} \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: 3120\: = \: P \: × \: \frac{4 \: \times 5 \: }{100} \: = 0.04 \: \times \: 5 \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: P \: = \: \frac{3120}{0.04 \: \times \: 5} \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Principal \: = \: ₹15600}} }\\ \\\end{gathered}\end{gathered}$
