Question:

If Company C belonged to the Cement or the IT industry and did announce extraordinarily good results, then which of  these statement(s) would necessarily be true? 

I . Venkat earned not more than 36.25% return on average.

II. Venkat earned not less than 33.75% return on average.

III. If Venkat earned 33.75% return on average, Company A announced extraordinarily good results.IV. If Venkat earned 33.75% return on average, Company B belonged either to Auto or to Steel Industry.

Explanation:

Company C gave a return of Rs. 60.

∴ Total returns will be the minimum possible when B gives 1.5 times the initially expected returns.

∴ Total returns would be 20 + 15 + 60 + 40 = Rs.135 = 33.75% of the initial investment.

Statement II is true.

Also, when returns are 33.75%, company B belongs to Auto or Steel Industry. Statement IV is true and Statement III is false.

Total returns will be the maximum possible when D gives 1.5 times the initially expected returns.

∴ Total returns would be 20 + 10 + 60 + 60 = Rs.150 = 37.5% of the initial investment.

Statement I is false.

Hence, option (b).
