Question 01
Find number of zeros in following expressions
12 * 15 * 5 * 24 * 13 * 17
The Question can be easily solved if you can find the number of (2 * 5) combination in the expression
Step 1
Reformulating the expression into simpler form
Step 2
Number of 2 in above expression = 5
Number of 5 in above expression = 2
So there are only two possible combinations of (2 * 5)
Thus there will be two zeros in above expression
