Correct Question:

Find the simple interest on a sum of rupees 2,000 at $5 \frac{1}{2} \%$per annum from 8 June 2015 to 19 August 2015.

Answer:

• Simple Interest = ₹ 22

Given:

• Principal = ₹ 2,000
• Rate of interest = $5 \frac{1}{2} \%$ = $\frac{11}{200}$
• Time = 8 June 2015 to 19 August 2015

Need To Find:

• Simple Interest = ?

Explanation:

Let us calculate the number of days from 8 June to 19 August 2015.

• June - 23 days (30 - 8 + 1)
• July - 31 days
• August - 19 days

Time = (23 + 31 + 19) days

⠀⠀⠀ = 73 days = 73/365 years

⠀⠀⠀ = 1/5 years (Table of 73)

Simple Interest = $\mathsf {\frac{2000 \times 11}{200} \times \frac{1}{5} }$
