Question

On what date will ₹ 1,950 lent on 5th January 2011 amount to ₹ 2, 125.50 at 5 per cent per annum simple interest?

$\rule{300}{1}$

Answer

Principal ⇒ ₹ 1950

Rate ⇒  5% per annum

Time ⇒ x

Simple Interest ⇒ Total Amount - Principal

⇒ 2125.50 - 1950  

⇒ Rs. 175.50

∴ Simple Interest  = $\sf \frac{Principal\times Rate\times Time}{100}$

=> $175.50 =\frac{ 1950\times 5\times x}{100}$

=> $100\times 175.50 =100\times \frac{ 1950\times 5\times x}{100}$

=> $17550=(1950)(5)x$

=> $9750x=17550$

=>  $\frac{9750x}{9750}=\frac{17550}{9750}$

=> $x= \frac{9}{5}$

Time ⇒ $(\frac{9}{5}\times 365) = 657$

∴ The date is 657 days after 5th January 2011.

∴ The date is 23rd October 2012.
