Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (7, 12, 25) (6, 9, 21)
Option 1: (9, 13, 24)
Option 2: (5, 8, 19)
Option 3: (8, 14, 24)
Option 4: (4, 11, 20)
Correct Answer: (5, 8, 19)
Solution : Given: (7, 12, 25); (6, 9, 21)
The logic here is – (The first number + The second number + 6) = The third number (7, 12, 25)→7 + 12 + 6 = 19 + 6 = 25 (6, 9, 21)→6 + 9

Question : Directions: Select the letter cluster that can replace the question mark (?) in the given letter cluster series. UKS, ZPX, EUC, JZH, ?
Option 1: ODN
Option 2: OEM
Option 3: PEM
Option 4: ODM
Correct Answer: OEM
Solution : Given: UKS, ZPX, EUC, JZH, ?
Add 5 to each letter of the previous term to obtain the next term in the series – UKS→U + 5 = Z; K + 5 = P; S + 5 = X ZPX→Z +
Question : Circum-centre of $\triangle PQR$ is O. If $\angle QPR=55^{\circ}$ and $\angle QRP=75^{\circ}$, What is the value (in degree) of $\angle OPR$?
Option 1: 45°
Option 2: 40°
Option 3: 65°
Option 4: 70°
Correct Answer: 40°
Solution : In $\triangle$PQR we have, $\angle$QPR = 55° and $\angle$QRP = 75° ⇒ $\angle$PQR = 180° – (55° + 75°) = 180° – 130° = 50° ⇒ $\angle$POR = 2 × $\angle$PQR = 2 × 50° = 100° In $\triangle$OPR, $\angle$OPR = $\angle$ORP [since OR =

Question : PQR is an equilateral triangle inscribed in a circle. S is any point on the arc QR. Measure of $\frac{1}{2} \angle \mathrm{PSQ}$ is:
Option 1: 20°
Option 2: 15°
Option 3: 30°
Option 4: 60°
Correct Answer: 30°
Solution :
Since PQR is an equilateral triangle inscribed in a circle, each of its angles is 60°. $\angle PSQ=\angle QRP = $ 60° (Angles in the same segment) $\frac{1}{2}\times \angle PSQ=\frac{60°}{2}=30°$ Hence, the correct answer is 30°.
Question : What is the value of $111\frac{1}{2} + 111\frac{1}{6} + 111\frac{1}{12} + 111\frac{1}{20} + 111\frac{1}{30}?$
Option 1: $111\frac{1}6$
Option 2: $111\frac{5}6$
Option 3: $555\frac{5}6$
Option 4: $555\frac{1}6$
Correct Answer: $555\frac{5}6$
Solution : $111 \frac{1}{2} + 111 \frac{1}{6} + 111\frac{1}{12}+111 \frac{1}{20} + 111\frac{1}{30}$ = $5\times 111+( \frac{1}{2} + \frac{1}{6} + \frac{1}{12}+\frac{1}{20} + \frac{1}{30})$ = $555+( \frac{1}{1\times 2} + \frac{1}{2\times 3} + \frac{1}{3\times 4}+\frac{1}{4\times 5} + \frac{1}{5\times 6})$ = $555+(\frac{1}{1}-\frac{1}{2} + \frac{1}{2} -\frac{1}{3}+ \frac{1}{3}-\frac{1}{4}+\frac{1}{4}-\frac{1}{5} + \frac{1}{5}-\frac{1}{6})$ = $555 +(\frac{1}1-\frac{1}6)$
