Numerical Ability
given that a and b are two prime numbers,while n is a natural number,such that
1/a+1/b+1/ab=1/n. find the value of ||a-b|-n|.
a) 4 b) 0 c)2 d)1
Read Solution (Total 2)
-
- a=2 and b=3 so ab=6
oR lets a=3 and b=2 then also ab=6
Now (1/2)+(1/3)+(1/6)=1
So, n=1
& | |2-3|-1 |=0
0r | |3-2|-1 |=0
