For how many sectors did the actual number of placements increase from 2015 to 2017 ?

  • A.5
  • B.2
  • C.3
  • D.4

Answer: D

Placements rose in 4 sectors.

Compare the actual numbers, 2015 (out of 800) against 2017 (out of 1200):

Sector20152017
Systems/IT184468
General Management96288
Operations/Supply chain160192
Marketing/Sales88156
Consulting11260
Others16036

Systems/IT, General Management, Operations/Supply chain and Marketing/Sales increased; Consulting and Others fell. Operations is the case to watch: its share fell from 20% to 16%, yet the number rose because the total grew from 800 to 1200, so counting by percentages alone gives 3, a wrong answer.
