Option 1: 255
Option 2: 260
Option 3: 275
Option 4: 270
Correct Answer: 255
Solution : Let the three numbers be a, b and c. According to the question, a2 + b2 + c2 = 323 and a2 + b2 = 2c ⇒ c2 + 2c = 323 ⇒ c2 + 2c – 323
Question : Directions: A plane flies 100 km west, then turns south and flies 150 km, then turns west and flies 300 km, then turns to its right and flies 150 km. Where is it now with reference to its starting position?
Option 1: 400 km east
Option 2: 200 km west
Option 3: 400 km west
Option 4: 200 km east
Correct Answer: 400 km west
Solution : Firstly, we will draw the diagram as per the given instructions –
Now, we have to find the distance from the starting point to the endpoint –

Question : Directions: Select the related letter cluster from the given alternatives. ZXVT : ACEG :: SQOM : ?
Option 1: FHJL
Option 2: HJLN
Option 3: JLMO
Option 4: IKMO
Correct Answer: HJLN
Solution : Given: ZXVT : ACEG :: SQOM : ?
Like, opposite letters of ZXVT – Z→A; X→C; V→E; T→G Thus, ZXVT is related to ACEG. Similarly, follow the same pattern for SQOM – S→H; Q→J; O→L; M→N
So, SQOM is related to HJLN. Hence, the second
Question : In the given figure, $\Delta QPS \cong \Delta SRQ $. Find the measure of $\angle PSR$.
Option 1: 64°
Option 2: 74°
Option 3: 52°
Option 4: 82°
Correct Answer: 74°
Solution : $\triangle$QPS = $\triangle$SRQ $\angle$QPS = $\angle$SRQ (Congruent part of congruent triangles) So, 106° = 2x + 12° ⇒ 106° – 12° = 2x ⇒ 94° = 2x $\therefore$ x = 47° $\angle$QPS = $\angle$SRQ = 106° So, PQRS is a parallelogram. $\angle$QSR = 180° –
