Solve using approximations:

p = 0.7197 / (0.294)(0.739)
p = 0.71 / (0.3)(0.7)

It'll give us the range between 3 & 4
Hence,  D

In the video from GMATNinja, in Step 3, how does he justify multiplying the 0.29 by 10 but NOT multiplying 0.74 by 10 at the same time? He goes on to multiply .74 by 100. This makes his math correct but it was confusing to me.

Bunuel · Answer

Basically, steps 2, 3, and 4 are just used to transform the decimals into integers. This could have been done in several ways.

One way is the method shown in the video solution. Another way would be to multiply 0.3 and 0.74 by 10 and 100, respectively, so by 1,000 overall. This would give 3 * 74 in the denominator.

Then, to balance this, we would also need to multiply 0.72 by 1,000, which would give 720. Thus, we would get the same expression:

720/(3 * 74)
