Question

in what time will rupees 7500 amount to rupees 8625 is simple interest is reckoned at 15 by 2% per annum​

Answer 1

Answer:

The time needed is 2 years.

Step-by-step explanation:

The formula to compute the simple interest is:

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

Given:

P = Rs. 7500

A = Rs. 8625

r = 15/2% = 7.5%

The interest earned is:

I = A - P = 8625 - 7500 =  1125

Compute the value of t as follows:

$SI=\frac{P\times r\times t}{100}\\t=\frac{SI\times100}{P\times r} \\=\frac{1125\times100}{7500\times7.5}\\=2$

Thus, the time needed is 2 years.
