Question

♡+♡+♡+♡+♡=30 by using 5 digit u can alsp rrpeat the number1,3?5,7,9,11,23,15

Answer 1

see  we cannot get an even no. from 5 odd nos. so ,it is not possible to make 30 from these nos.

Answer 2

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.
