Question

Find the time period ( n ) for which money is borrowed for the following cases. (a). P = 6,500, r = 6 % , I = 400.
SOLUTION.
​

Answer 1

Answer:

Given :-

• A sum of Rs 6500, rate of interest is 6% and the simple interest is Rs 400.

To Find :-

• What is the time period.

Formula Used :-

$\clubsuit$ Time Period Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{n =\: \dfrac{S.I. \times 100}{P \times r}}}}\: \: \: \bigstar$

where,

• n = Time Period
• S.I. = Simple Interest
• P = Principal
• r = Rate of Interest

Solution :-

Given :

• Principal (P) = Rs 6500
• Rate of Interest (r) = 6%
• Simple Interest (S.I.) = Rs 400

According to the question by using the formula we get,

$\implies \sf\bold{\blue{n =\: \dfrac{S.I. \times 100}{P \times r}}}$

$\implies \sf n =\: \dfrac{400 \times 100}{6500 \times 6}$

$\implies \sf n =\: \dfrac{40\cancel{000}}{39\cancel{000}}$

$\implies \sf n =\: \dfrac{40}{39}$

$\implies \sf n =\: 1.02$

$\implies \sf n \approx 1$

$\implies \sf\bold{\red{n =\: 1\: years}}$

$\sf\bold{\purple{\underline{\therefore\: The\: time\: period\: (n)\: is\: 1\: years\: .}}}$
