Question

i want to get a total of 30.if the given numbers are 1,3,5,7,9,11,13,15. you can add the same numbers.but in three steps

Answer 1

When adding odd number we do not get answer of even number..! So it is possible through - FACTORIAL method...! So the ans :- 3 !+ 15+9= 30 !!

Answer 2

here can be many answers but the basic idea is using factorial. Factorial is the product of all the numbers from 1 to that number. For example 4! = 1 x 2 x 3 x 4 = 24.
 
So, 3! + 11 + 13  = 30
Similarly you can find many such answers.

Hope that helps !!
