Answer 2

Answer:

Given :-

• The rate of interest is 2.5%, time period is 2 years and the simple interest is Rs 100.

To Find :-

• What is the principal amount.

Formula Used :-

$\clubsuit$ Principal Formula :

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

where,

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

Solution :-

Given :

• Rate of Interest = 2.5%
• Time Period = 2 years
• Simple Interest = Rs 100

According to the question by using the formula we get,

$\implies \bf P =\: \dfrac{S.I \times 100}{R \times n}$

$\implies \sf P =\: \dfrac{100 \times 100}{2.5 \times 2}$

$\implies \sf P =\: \dfrac{\cancel{10000}}{\cancel{5}}$

$\implies \sf P =\: \dfrac{2000}{1}$

$\implies \sf\bold{\red{P =\: Rs\: 2000}}$

$\therefore$ The principal amount is Rs 2000 .
