Neha this is done using calculator. (ln 1.015= 0.0148). But its actually a problem because a simple calculator which is allowed in the exam doesn't have a log (ln) button! In that case we can eliminate options B and D because value of log 1.015 in denominator can't be greater than 1.015.( hope you know this is because log x < x for all x>o) But still we can't eliminate further b/w options a and c without access to a calculator with log button!

In any case Vaibhav's method is with us which doesn't need any calculator and is simple enough!
Vaibhav, could you please (for my concept clarity) tell me if my method is wrong?? Is it not for instantaneous growth?? Then why is the answer coming the same?
