In question below is given a statement followed by two conclusions I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement.
Statement: In one day cricket match, the total runs made by a team were 200 . Out of these 160 runs were made by spinners.

Conclusions:
I. 80% of the team consists of spinners.
II. The opening batsmen were spinners.​​

Statement: In one day cricket match, the total runs made by a team were 200. Out of these 160 runs were made by spinners.

Conclusions:
I. 80% of the team consists of spinners.

The statement only states runs scored by spinners, not the number of players who are spinners.
Just because spinners contributed 80% of the runs, it does not necessarily mean 80% of the team consists of spinners.
Does not logically follow.
II. The opening batsmen were spinners.​​

The statement provides no information about who the opening batsmen were. We cannot conclude that they were spinners.

Thus, the correct option is (d) If neither I nor II follows.
