1.	What time will it take for a sum to amount to three times itself at 12% per annum under simple interest ?
Answer» Let T years be the required time period. Given that, Amount `(A)=3 xx ` Principal (P) `therefore P(1+(TR)/(100))=3P` `implies 1+(12T)/(100)=3 implies T=(200)/(12)=16(2)/(3)` years Hence, required time period`=16(2)/(3)` years.
