The banker's gain of a certain sum due 2 years hence at 10% per annum is Rs. 24. The present worth is:
Answer: Option
Explanation:
| T.D. = |  |
B.G. x 100 |  |
= Rs. | |
24 x 100 | |
= Rs. 120. |
| Rate x Time | 10 x 2 |
 P.W. = |
100 x T.D. | = Rs. | |
100 x 120 | |
= Rs. 600. |
| Rate x Time | 10 x 2 |

Is the answer correct?
I mean B.G = B.D - T.D.
Now, B.D = (PxRxT)/100.
T.D = (PxRxT)/(100+ RxT).
Now, R=10; T=2; B.G = 24.
Solving this we get P = 720.
Am I doing anything wrong? Appreciate the help.

Can it be done through compound interest?

How T.D. = B.G.*100/(Rate*Time)?

Someone please show the derivation.
B.G. = (T.D.)*(T.D.)/P.W. or
T.D. = B.G.*100 /(Rate*Time).
B.G. = (T.D.)*(T.D.)/P.W. or
T.D. = B.G.*100 /(Rate*Time).

Simple method as for I know.
T.D. =(B.G. x 100)/(R/T)= (24*100)/(10*2)=Rs.120.
B.G=(T.D)^2/P.W => P.W= (T.D)^2/B.G.
P.W= (120)^2/ 24 = 14400/24=600.
If anyone knows better explanation?
T.D. =(B.G. x 100)/(R/T)= (24*100)/(10*2)=Rs.120.
B.G=(T.D)^2/P.W => P.W= (T.D)^2/B.G.
P.W= (120)^2/ 24 = 14400/24=600.
If anyone knows better explanation?

100 is there because rate is specified as a percentage. Just cross multiply the equation P=[(S.I) *100/ (R. T) ]
