In what time will RS 1860 amount to RS 2641.20 at simple Interest of 12 % per annum? 

plz check my answer is correct 

Given:

Principal (P) = Rs 1860

Interest Rate (R) = 12 %

Amount = 2641.20


•°• SI = 2641.20 -1860

= 781.20

Hence, SI = 781.20


To find ; Time =?

According to the Statement!

We know that Formula of simple interest;





SI = P× R× T/100

=> 781.20 = 1860 × 12 × T/100

=> 781.20 × 100 = 22,320 × T

=>78120 = 22,320 × To

=> T= 78120/22,320

•°• Time = 3.5 Years!!


Conclusion; 

3.5 Years time will RS 1860 amount to RS 2641.20 at simple Interest of 12 % per annum.
