A) 10 yr
B) 15 yr
C) 20 yr
D) 25 yr
Correct Answer: C
Solution :
\[A=2P\] \[\therefore \] \[SI=P\] \[(SI=2P-P)\] \[P=\frac{P\times r\times 10}{100}\] \[\therefore \] \[r=10%\] So, the new amount = 3P But the new \[SI=2P=(3P-P)\] \[2P=\frac{P\times 10\times t}{100}\] (r = 10%) \[\therefore \] \[t=20\,yr\]You need to login to perform this action.
