The idea of Word substitution, sentence codes, word formation

Three formats share this subconcept. Sentence codes: a few sentences and their coded forms are given; words that recur pin down their codes by intersection, and the rest follow by elimination (JIPMAT 2021: 'sik' = red). Word swaps: a chain of "X is called Y" statements; the question asks a fact and wants the code word for the true answer (Rohtak 2019: the king of the jungle is told as Goat). Word formation: which word can or cannot be made from the letters of a given word (JIPMAT 2021, 2024).

The exam method

  1. Most frequent word first. 'is' appears in all three sentences and only '9' is in all three codes: is = 9.
  2. Pairs of sentences. 'flowers' is in two sentences; their common code is hee. Then the sentence 'red flowers' = 'sik hee' leaves sik for red.
  3. Leftovers. In 'fly on painted sky', fly, on and painted are known from other sentences, so sky takes the remaining code.
  4. Joined words. bike and 'and' appear only together in two sentences with codes tm and ts: nothing separates them.
  5. Swaps. answer the fact (the national fruit is the mango), then read the chain once: Mango is called Papaya.
  6. Formation. tick off letters; SOLACE needs an E that MIRACULOUS lacks.
