Question : Directions: Which of the following letter clusters will replace the question mark (?) in the given series to make it logically complete? ADZ, GJF, MPL, SVR, ?
Option 1: XYB
Option 2: YBX
Option 3: XBY
Option 4: YXB
Correct Answer: YBX
Solution : Given: ADZ, GJF, MPL, SVR, ?
Add 6 to each letter cluster to get the next term in the given series – ADZ→A + 6 = G, D + 6 = J, Z + 6 = F→GJF GJF→G + 6 = M, J + 6

Question : The heights of two right circular cones are in the ratio 1 : 5 and the perimeter of their bases are in the ratio 5 : 3. Find the ratio of their volumes.
Option 1: 8 : 11
Option 2: 7 : 6
Option 3: 5 : 9
Option 4: 3 : 4
Correct Answer: 5 : 9
Solution : The volume of a cone, where $r$ is the radius and $h$ is the height. $V = \frac{1}{3}\pi r^2 h$ Given that the heights of the cones are in the ratio 1 : 5. Let the height of the first cone be $h$
Question : Directions: After interchanging the given two numbers what will be the values of equations (I) and (II) respectively? 8 and 4 I. 8 – 4 × 6 ÷ 3 + 7 II. 8 × 3 – 6 ÷ 2 + 4
Option 1: –5 and 20
Option 2: –4 and 18
Option 3: –5 and 17
Option 4: 20 and 18
Correct Answer: –5 and 17
Solution : Given: I. 8 – 4 × 6 ÷ 3 + 7 II. 8 × 3 – 6 ÷ 2 + 4
On interchanging 8 and 4 in the above equations we get – Equation I: 4 – 8 × 6 ÷ 3 +

Question : An isosceles triangle ABC is right-angled at B. D is a point inside the triangle ABC. P and Q are the feet of the perpendicular drawn from D on the sides AB and AC respectively of ABC. If $AP = a$ cm , $AQ = b$ cm and $\angle$BAD = 15°, $\sin$ 75°= ?
Option 1: $\frac{2b}{\sqrt 3 a }$
Option 2: $\frac{a}{2b}$
Option 3: $\frac{\sqrt 3a}{2b}$
Option 4: $\frac{2a}{\sqrt 3b}$
Correct Answer: $\frac{\sqrt 3a}{2b}$
Solution : Since $\triangle$ABC is a right-angled isosceles triangle, $\angle$A = $\frac{180 - 90}{2}$ = 45° $\angle$DAQ = $\angle$A–$\angle$BAD = 45° – 15° = 30° $\sin$ $\angle$ADQ = $\sin$ 60° = $\frac{AQ}{AD}$ $\frac{b}{AD}$ = $\frac{\sqrt3}{2}$ AD = $\frac{2b}{\sqrt3}$ From $\triangle$APD, $\sin$ 75° = $\frac{AP}{AD}$ = $\frac{a}{\frac{2b}{\sqrt3}}$
Question : A man gives 50% of his money to his son and 30% to his daughter. 80% of the rest is donated to a trust. If he is left with Rs. 16,000 now, how much money did he have in the beginning?
Option 1: Rs. 40,000
Option 2: Rs. 8,00,000
Option 3: Rs. 80,000
Option 4: Rs. 4,00,000
Correct Answer: Rs. 4,00,000
Solution : Let us assume the income of the man is Rs. $x$. According to the question, he gives 50% of his money to his son and 30% to his daughter. $\therefore$ The money he is left with = $x-\frac{x}{2}-\frac{3x}{10}$ $= \frac{10x-5x-3x}{10}$ $=\frac{2x}{10}=\frac{x}{5}$ According to the
Question : Directions: What should come in place of the question mark (?) in the given series? 339, 340, 348, ?, 439
Option 1: 377
Option 2: 492
Option 3: 380
Option 4: 375
Correct Answer: 375
Solution : Given: 339, 340, 348, ?, 439
Add the cubes of the consecutive numbers (starting from 1) to each term to get the next term in the series. 339 + (1)3 = 339 + 1 = 340 340 + (2)3 = 340 + 8
