Question

what is the rate of interest if rupees 3750 amounts to rupees 4650 in 4 years

Answer 1

Given principal = 3750, Amount = 4650, T = 4 years.

We know that SI = Amount - Principal

                            = 4650 - 3750

                            = 900.


We know that SI = PTR/100

                        $R = \frac{100 * SI}{P * T}$
                
                                   = $\frac{100 * 900}{3750 * 4}$

                                   = 90000/15000

                                   = 6%.


Therefore the Rate of interest = 6%.


Hope this helps!

Answer:

S.I *100/p*t
