Question : The value of $\frac{\sin ^2 30^{\circ}+\cos ^2 60^{\circ}-\sec 35^{\circ} \cdot \sin 55^{\circ}}{\sec 60^{\circ}+\operatorname{cosec} 30^{\circ}}$ is equal to:
Option 1: $\frac{1}{8}$
Option 2: $-\frac{1}{4}$
Option 3: $\frac{1}{4}$
Option 4: $-\frac{1}{8}$
Correct Answer: $-\frac{1}{8}$
Solution : Given: $\frac{\sin ^2 30^{\circ}+\cos ^2 60^{\circ}-\sec 35^{\circ} \cdot \sin 55^{\circ}}{\sec 60^{\circ}+\operatorname{cosec} 30^{\circ}}$ = $\frac{(\frac{1}{2})^2+(\frac{1}{2})^2 - \sec 35^{\circ} \cdot \sin (90-35)^{\circ}}{2+2}$ = $\frac{(\frac{1}{4})+(\frac{1}{4}) - \sec 35^{\circ} \cdot \cos 35^{\circ}}{2+2}$ = $\frac{(\frac{2}{4}) - (\frac{1}{ \cos 35^{\circ}}) \cdot \cos 35^{\circ}}{4}$ = $\frac{(\frac{2}{4}) - 1}{4}$ = $-\frac{1}{8}$ Hence, the
Question : Directions: If 1 / 4 / 3 = 254 and 3 / 6 / 8 = 479, then 5 / 2 / 7 = ?
Option 1: 416
Option 2: 461
Option 3: 368
Option 4: 638
Correct Answer: 638
Solution : Given: 1 / 4 / 3 = 254; 3 / 6 / 8 = 479
1 / 4 / 3→1 + 1 = 2; 4 + 1 = 5; 3 + 1 = 4→254 3 / 6 / 8→3 + 1 = 4; 6 +
Question : Directions: If + means ×, × means –, – means ÷ and ÷ means +, then what will come in place of the (?) in the following equation? 250 – 10 + 10 × 5 ÷ 2 = ?
Option 1: 247
Option 2: 167
Option 3: 320
Option 4: 234
Correct Answer: 247
Solution : Given: 250 – 10 + 10 × 5 ÷ 2 = ?
After interchanging the given mathematical signs, we get – ⇒ 250 ÷ 10 × 10 – 5 + 2 ⇒ 25 × 10 – 5 + 2 ⇒ 250 – 5 + 2
Question : If the hypotenuse of an isosceles right-angled triangle is 10 cm, then the other two sides (in cm) are __________.
Option 1: $10\sqrt{2}$ and $10\sqrt{2}$
Option 2: $8\sqrt{2}$ and $8\sqrt{2}$
Option 3: $6\sqrt{2}$ and $6\sqrt{2}$
Option 4: $5\sqrt{2}$ and $5\sqrt{2}$
Correct Answer: $5\sqrt{2}$ and $5\sqrt{2}$
Solution : Given: Hypotenuse of the isosceles right-angled triangle = 10 cm Let the other two equal sides be $x$ cm. Now applying the Pythagoras theorem, we get, $x^2+x^2=10^2$ ⇒ $2x^2=100$ $\therefore x=\sqrt{50}=5\sqrt{2}$ Hence, the correct answer is $5\sqrt{2}$ and $5\sqrt{2}$.

Option 4: 84, 86, 89, 88
Correct Answer: 46, 48, 49, 44
Solution : Given: APES
Number representations of each letter – A→46, 68, 89, 94 P→48, 66, 84, 99 E→49, 64, 88, 96 S→44, 69, 86, 98
First option: 46, 48, 49, 44; All the letters of the word APES can be represented through this
Question : Pipes A and B can fill a tank in 16 hours and 24 hours, respectively, whereas pipe C can empty the full tank in 40 hours. All three pipes are opened together, but pipe A is closed after 10 hours. After how many hours will the remaining part of the tank be filled?
Option 1: $12 \frac{1}{2}$
Option 2: $10$
Option 3: $20$
Option 4: $15\frac{1}{2}$
Correct Answer: $12 \frac{1}{2}$
Solution : Pipe A can fill in 1 hour = $\frac{1}{16}$ Pipe B can fill in 1 hour = $\frac{1}{24}$ Pipe C can empty in 1 hour = $\frac{1}{40}$ Together they can fill in 1 hour $=\frac{1}{16} + \frac{1}{24} – \frac{1}{40}=\frac{19}{240}$ Together they can fill in
Question : Directions: Some equations are solved based on a certain system. Find the correct answer for the unsolved equation on that basis. 5 * 6 = 35; 8 * 4 = 28; 6 * 8 = ?
Option 1: 46
Option 2: 34
Option 3: 23
Option 4: 38
Correct Answer: 46
Solution : Given: 5 * 6 = 35; 8 * 4 = 28; 6 * 8 = ?
Like, 5 * 6 = 35→5 + (6 × 5) = 5 + 30 = 35 8 * 4 = 28→8 + (4 × 5) = 8 + 20
