Answer 2

Question

Find S.I. for the following :-

a. Rs. 68,000 at $\sf 16{\dfrac{2}{3}}$% p.a. for 3 years.

Given

• Principal = Rs. 68,000
• Rate % = $\sf 16{\dfrac{2}{3}}$%
• Time = 3 years

To find

• Simple Interest

Solution

Using formula,

$\quad\purple{ \bigstar} \boxed{ \sf{S.I. = \dfrac{P \times R \times T}{100}}}$

where,

• P = Principal
• R = rate%
• T = Time

Substituting the given values,

$\quad \implies \sf \dfrac{68000 \times 50 \times 3 }{100 \times 3} \\ \\ \\ \quad \implies \sf \dfrac{680 \not0 \not0 \times 50 \times \not3 }{1 \not0 \not0 \times \not3} \\ \\ \\ \quad \implies \sf 680 \times 50 \\ \\ \\ \quad \implies \sf Rs. 34000$

$\therefore$ Simple Interest = Rs. 34,000
