Answer 1

Principal = 100

Time = 4 years

Rate = 17

PTR/100 = S. I

$\frac{100 \times 4 \times 17}{100} \\ \\ = = > 68$

Simple interest = 68₹

Answer 2

ANSWER

Given=>

Principal = 100

Time = 4 years

Rate of interest = 17 per annum.

Now we know that =>

$\dfrac{PTR}{100}$ = S. I

=>S. I=$\dfrac{100\times4\times17}{100}$

=>S. I=Rs68

or

Simple interest = 68₹

Hence Amount = Rs 168.

Remember

1)Simple interest=$\dfrac{PTR}{100}$

2)Amount = Simple interest + principal.
