Question

in what time will 1800 yield simple interest of 390 at rate of 5% per annum​

Answer 1

Answer:

Formula:-

(SI=PRT/100)

>SI-390

>P-1800

>R-5/365

390=1800*5*T/100*360(>>leave 5 days and add with the final result, its helps in easy calculation).

T=1560(and add 5 days with this result)

T=1560+5=1565.

T=1565 days,

x=4years=1460 days,

T-x=1565-1460=105 days,

105 days= 3months 5 days.

Result.:4 years 3 months & 5 days.

Final Ans-> 4 years & 3 months approx.
