Classification Reasoning PYQ Practice Test – Set 1

Pattern: {1st letter - 9 = 4th letter} and {2nd letter - 1 = 3rd letter}. QKJH -> Q(17)-9=H(8), K(11)-1=J(10). SMLJ -> S(19)-9=J(10), M(13)-1=L(12). WQPN -> W(23)-9=N(14), Q(17)-1=P(16). But in OIGE -> O(15)-10=E(5), I(9)-2=G(7) which does not follow the rule.

Except 'Prowl', all other words refer to making a loud sound or cry. 'Prowl' means to move around quietly.

Pattern: ($a^2 - 1)$ : ($a^3 - 1)$. 3 : 7 = ($2^2 - 1)$ : ($2^3 - 1)$. 15 : 63 = ($4^2 - 1)$ : ($4^3 - 1)$. 8 : 26 = ($3^2 - 1)$ : ($3^3 - 1)$. Option (d) 23 : 123 does not follow this rule (should be 24 : 124 for $a=5$).

Pattern: Each letter increases by +2. O(+2)Q(+2)S, J(+2)L(+2)N, H(+2)J(+2)L. In MOP: M(+2)O(+1)P, so it does not follow the pattern.

Except Hypertension, all three are joint/bone disorders or deficiency ailments. Hypertension refers to high blood pressure.
