 Quantitative Aptitude (1) What is the number of zero's at the end of the product of the numbers from 1 to 100? Sol: To find out the number of trailing zeros, we first need to acknowledge the times 10s can be produced in the factorial sequence: 1x2x3x4x5....x100 Since 10s are made when an even# meets 5  in the sequence, then: → (100/5) + {100/(5*5)} = 20 + 4 Or 24, will be the needed answer.

Data Science Machine Learning Tech Problems: My 5 cents I like to flex my funny bones or explain things from the base up so if you want to cut the crap you can  💁 directly refer to the information in the emoji-highlighted text to get a quick purview of things.   Hope to include cool graphs, mind maps and cartoons to supplement max learning.
