[nelloriumrao]

Hi,
If anyone could please answer these 2 questions

1. x, y, and z are integers greater than 1, what is value of x + y + z?
a. xyz = 70
b. x/yz = 7/10
2. n and m are positive integers, what is remainder when 34n + 2 + m is divided by 10?
a. n = 2
b. m = 1

No:1 IMO is A and NO:2 IMO C, plz confirm

[RB_51273]

No 1 is quite good one,IMO should be A only as only three prime factors of 70 and those will represent the x,y,and z.

tks
