Question

find the principal that will yield an interest of rupees 367.50 in 4 whole 1 by 2 years and 3 whole 1 by 3 % per annum​

Answer 1

The principal amount is Rs. 2450.

Step-by-step explanation:

The formula to compute simple interest is:

$SI=\frac{P\times r\times t}{100}$

The information provided is:

SI = Rs. 367.50

t = $4\frac{1}{2}=4.5$ years

r = $3\frac{1}{3}\%=\frac{10}{3}\%$ p.a.

Compute the value of the principal as follows:

               $SI=\frac{P\times r\times t}{100}$

         $367.50=\frac{P\times 10\times 4.5}{3\times 100}$

$367.50\times 300=P\times 10\times 4.5$

         $110250=45P$

                 $P=\frac{110250}{45}$

                 $P=2450$

Thus, the principal amount is Rs. 2450.
