if |x|=x ,x>=0
|x|=-x,x
Read Solution (Total 10)
-
- draw the graph,it can be seen that
minimum value of |x|+|x-1|+|x-2| will be at x=1
and value is =1+0+1=2
ans- 2 - 11 years agoHelpfull: Yes(51) No(3)
- if we take x=0 then we get |x|=x so |x|+|x-1|+|x-2|=x+x-1+x-2=3x-3 X=0,,so minmum value is -3.

- Here the each term of series are in ap..such that..
1) 6,11,16...,996 2) 7,12,17....,997. 3) 8,13,18,....,998 4) 9,14,19,.....,999.
Here if we add each term of each series in position wise then we get a number which is divisible by 10.
So take any series we get similar ans.
a/c to a.p,
996=6+(n-1)5
198=(n-1)
So, n =199. We can't take 1,2,3,4 as it contain 1.
so required ans is 199. - 9 years agoHelpfull: Yes(0) No(0)
