Let P.W. be Rs. *x*.

Then, S.I. on Rs. *x* at 16% for 9 months = Rs. 189.

x x 16 x |
9 | x | 1 | = 189 or x = 1575. |

12 | 100 |

P.W. = Rs. 1575.

Sum due = P.W. + T.D. = Rs. (1575 + 189) = Rs. 1764.

TD = AMT * R * T/100+(R * T)

TD = 189, R=16,T=3/4

189 = Amt * 3/4 * 16/100+(16 * 3/4).

Amt = 1764.

TD = 189, R=16,T=3/4

189 = Amt * 3/4 * 16/100+(16 * 3/4).

Amt = 1764.

" at 16% per annum is Rs. 189"- So amount Rs. 189 is for 12 months as it is given per annum, isn't it?

Then how come "S. I. On Rs. X at 16% for 9 months = Rs. 189"- is this Rs. 189 for 9 months?

Kindly help!

@Subrat.

Amount = (Present Worth(PW)) + (True Discount (TD)).

Please check the "Important Formulas" which is available above left side.
