[@SourabhOjha-f9j]

39.4/1000 * 100 = 3.94
19.4/1000*100 = 1.94
so
3.94 - 1.94 = 2 % growth rate
so
200=100 (1+ 0.02) ^x
now try option
sol- a 35 yrs

Home work question
35 years 🎉 is the answer
P = 1000
A= 2000
R= 39.4-19.4= 20
20/1000=0.02
A= p(1+i)^t
2000=1000(1+0.02)^t
2000/1000= 1.02^t
2=1.02^t
35th poweR of 1.02= 2
T= 35 years 🎉

[@KTClasses_178]

39.4/1000×100 = 3.94
19.4/1000×100 = 1.94
3.94 - 1.94 = 2
2/100= 0.02
A = P (1+i/N)t× N
200 = 100 (1+0.02/1)t×1
200/100 = (1.02)t
2 = (1.02)t
After try the option answer is 35
