Question

What sum will yield an interest off 7840 in 2 years at 6 1/4 % per annum?

Answer 1

The simple interest is given as Rs7840 in 2 years at the rate of 25/4 %

We know that,

S.I.= P×R×T/100

Substituting the values in the above formula, we get,

7840 = P×25×2/4×100

P= 7840×4×100/25×2

P = Rs62720

Answer 2

Answer:

$\large{Simple \: Interest = ₹\: 7840}$

$\large{Rate = 6\frac{1}{4}\% = \frac{25}{4} \%}$

$\large{Time = 2 \: years}$

$\large {Principal \: = \frac{100 \times SI}{R \times T}}$

$\large{Principal = \frac{100 \times 7840 \times 4}{25 \times 2}}$

$\large{Principal = Rs \: 62720}$
