i)
3!+1+3+13+7=30 [ If
we solve by factorial method]
ii)
3!+3!+3!+3!+3!=30
[3!=3×2×1=6]
[without factorial
method]
Odd nos added for odd
nos. of time will always give an ODD NUMBER. Odd nos added for
even no of time will give an EVEN NUMBER.
3!+1+3+13+7=30 this solution is a little awkward i know but according to all of us we do not think there will be any other process other than using factorial
