Answer 1

$\huge \rm \underbrace \color {red}{required \: answer}$

Principal → rs.2000

Rate of interest → 5½% P.A

Time → 8 June 2015 to 19 August 2015

(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 days

= 1/5 years (Table of 73)

$\rm \bold{ \frac{2000 \times 11 \ }{200}} \times \frac{1}{5}$

$\rm \bold \color{blue}{ = rs.22}$
