Soln. At last i got my mistake....
In d previous post i hv considerd
"ppl who fail in Q.A.=ppl failed-ppl passed in Q.A."
Bt its incorrect apprehension.[ppl describd in d region may pass in Q.A.]
So obviously data is inadequate...
Option (d) is correct...
For nother problm above decesion remains same...
TAKEN AS A WHOLE MY SOLN. IS LIKE DS:
1.(a)
2.(d)
3.(d)
4.(d)
Giv ur best to d world.
