You have to use the numbers 1,2,3,4 and 5. Add those numbers and the sum should be equal to 50. You can combine the numbers to form tens (i.e 2 and 4 is 24) but you can only use the number once.Q: 12345=50

You can only use the number once and only addition is the operation accepted.

I think we must use two numbers which have two digits and one of them must be one digited number.If we try it we can say our numbers are xy,ab and c.

xy + ab + c = 50

10x+y+10a+b+c = 50

10(x+a) + y+b+c = 50

Think about y+b+c. Maximum it can be 5+4+3 = 12 but it can't because there is a number which is multiple of 10.So it can be 10 maximum and x+a must be 4.

We can only use 1+3. 40 + y+b+c = 50 , y+b+c = 10. And other numbers are 2+4+5 = 11.  10 doesn't equal to 11 and it says there isn't any solution for this problem :)
