Is 5^k less than 1000?
1)5^k+1>3000
2)5^k-1=5^k-500
I tried the following approach.Experts ,kindly let me know if this is correct
I got the answer to be D but the OA given is B.
My Approach.
1.If 5^k+1 has to be greater than 3000 then the least value of k should be atleast 4 since 5^5=3125>3000 and hence 5^4 <1000 from A
2.Using the statement 2 I tried random values for k which did not satisfy this condition except k=4
in which case again we can determine if 5^k <1000
Kindly explain why the OA is B.

Resilience is a trait that manifests in an individual when he/she faces consistent failures motivating them to succeed in the end.
