Question

what is the sum of money off which 3*3/4% is RS 45?​

Answer 1

Answer:

The sum is rs.3382.352

Step-by-step explanation:

Let the principal be x

Time = 3 years

Rate of interest = \frac{20}{3}\%

Formula : A=P(1+r)^t

A=x(1+\frac{20}{300})^3

A=1.2136x

Compound interest = Amount - principal = 1.2136x- x=0.2136x

Formula : SI = \frac{P \times R \times T }{100}

SI = \frac{x \times \frac{20}{3} \times 3 }{100}

SI = 0.2 x

Now we are given that the difference between the compound interest and simple interest is Rs.46

So, 0.2136x-0.2x = 46

0.0136x = 46

x = \frac{46}{0.0136}

x = 3382.352

Hence the sum is rs.3382.352

Answer 2
