  1. It is not possible to decide ascending order of these five as there is no sufficient information about Mike.
  2. Beena certainly ranks fourth when performance is arranged in descending order.
  3. Ashu's performance is not definitely of high quality when compared with other four.
  4. If we are not considering Mike then Dharm's performance is definitely of high quality than Karim and Beena.

iii)Beena's performance is of lower level than Karim.

Karim > Beena

iv) Ashu's performance level is higher than Mike.

Analyzing the options

i) It is not possible to decide ascending order of these five as there is no sufficient information about Mike. → True

ii) Beena certainly ranks fourth when performance is arranged in descending order. → False( It is possible but not definite)

iii) Ashu's performance is not definitely of high quality when compared with other four. → True( it is possible but not definite as performance of Ashu and Dharm cannot be compared).
