Answer 1

$\textbf{\huge{ANSWER:}}$

Given:

Principal = Rs. 500

Interest = Rs. 105

Rate of interest = 7/2%

The formula for calculating the Simple Interest:

I = P × R × T

=》 105 = 500 × 7/2 × T

=》 105 = 250 × 7 T

=》 105 = 1750 T

=》 T = 105/1750

=》 T = 0.06 years

Time = 0.06 Years

Hope it Helps!! :)

Answer 2

Here's the answer

Given =>

Principal = Rs.500

Interest = Rs. 105

Rate = 7/2% p. a [= 3.5% p. a]

To find =>

Time = ?

Solution =>

We know that,

Interest = Principal × Rate × Time

$\tt{105 = 500 × 3.5 × Time}$

$\tt{ \frac{105}{3.5} = 500 \times time}$

$\tt{30 = 500 \times time}$

$\tt{ \frac{30}{500} = time}$

$\tt{0.06 = time}$

Thus,

Time = 0.06 years
