Aptitude Question: Some HOTs

 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.

(2) X defies Y by banning (event) because of a scientific cause. Questions asks: The (event) which Y banned would most likely result in?...
