Question
If the compound interest on a certain sum at 1623 % to 3 years is Rs.1270, find the simple interest on the same sum at the same rate and f or the same period.
Options
A. 1080
B. 1090
C. 1180
D. 1109

Correct Answer

1080

Explanation

Let the sum be Rs. x. Then,

$C . I = [x * {(\frac{50}{300 * 100})}^{3} - x] = (\frac{343 x}{216} - x) = \frac{127 x}{216}$

$? \frac{127 x}{216} = 1270$

$x = 2160$

Thus, the sum is Rs. 2160

$S . I = R s . [2160 * \frac{50}{3} * 3 * \frac{1}{100}] = R s 1080$

Discuss

Correct Answer: Rs. 704

Explanation:

We know that,

$S . I . = \frac{PTR}{100} ? P = \frac{S . I x 100}{T x R} And also, C . I = P [{(1 + \frac{R}{100})}^{n} - 1]$

From given data, P = Rs. 8625

Now, C.I = $8625 [{(1 + \frac{4}{100})}^{2} - 1] = 8625 [{(\frac{26}{25})}^{2} - 1] = 8625 [\frac{676}{625} - 1] = 8625 x \frac{51}{625} C . I = Rs . 703.80$
