Passage beginning “Guest lectures on five subjects viz.,…”

Which lecture is scheduled between Statistics and English ?

cMathematics
dNo lecture

AnswerUPSC’s answer is (b).

The schedule runs Monday Statistics, Tuesday History, Wednesday English, Thursday Economics, Friday Mathematics. History can only be on Tuesday, and English, Economics and Mathematics must occupy consecutive days in that order, which pushes them to Wednesday through Friday and leaves Monday for Statistics. History on Tuesday lies between Statistics on Monday and English on Wednesday.

Why each option is right or wrong
  • (a) Wrong. Economics is on Thursday.
  • (b) Right. History on Tuesday falls between Statistics (Monday) and English (Wednesday).
  • (c) Wrong. Mathematics is on Friday.
  • (d) Wrong. One lecture, History, falls between them.
