Question

find the principal if the simple interest for 3 years at 5% is rupees 120​

Answer 1

Answer:

$\large\boxed{\sf{Rs.\;800}}$

Step-by-step explanation:

Let the principal is p

Also, it's given that,

• Simple intrest, SI = ₹ 120
• Time, t = 3 yrs.
• Rate % p.a, r = 5%

We know that,

SI = (p × r × t)/100

Substituting the respective values, we get,

$= > 120 = \dfrac{p \times 5 \times 3}{100} \\ \\ = > p = \frac{120 \times 100}{5 \times 3} \\ \\ = > p = 8 \times 100 \\ \\ = > p = 800$

Hence, the required principal is ₹ 800.
