Data Sufficiency (DS) | Re: What is the value of N? (1) N is the least integer such that

Solution

We need to find the value of N.

Since we are not given much information, let us analyse both the statements one byone.

Statement-1 “N is the least integer such that (0.0036) * (0.00078) * (6370) * 10^N is an integer. ”

Let us write\((0.0036) * (0.00078) * (6370) * 10^N\) in simplified form.

•\(= (0.0036) * (0.00078) * (6370) * 10^N\)
•=\((0.0036) * (0.00078) * (637) * 10^N*10\)
•=\((0.0036) * (0.00078) * (637) * 10 ^{(N+1)}\)
