Question : Directions: If 27 * 4 = 77 and 31 * 9 = 239, then 21 * 6 = ?
Option 1: 94
Option 2: 107
Option 3: 99
Option 4: 106
Correct Answer: 99
Solution : Given: 27 * 4 = 77 and 31 * 9 = 239
Like, 27 * 4 = 77→27 × 4 = 108; 27 + 4 = 31; 108 – 31 = 77 And, 31 * 9 = 239→31 × 9 = 279; 31 + 9
Question : PQR is an equilateral triangle and the centroid of triangle PQR is point A. If the side of the triangle is 12 cm, then what is the length of PA?
Option 1: $4 \sqrt{3}$ cm
Option 2: $8 \sqrt{3}$ cm
Option 3: $2 \sqrt{3}$ cm
Option 4: $\sqrt{3}$ cm
Correct Answer: $4 \sqrt{3}$ cm
Solution :
Given: PQR is an equilateral triangle and the centroid of triangle PQR is point A. The side of the triangle is 12 cm. The equilateral triangle circumradius = $\frac{\text{side}}{\sqrt3}$. The equilateral triangle's centres are all located at the same point. Whether it's a
Question : Two trains X and Y start from Jodhpur to Jaipur and from Jaipur to Jodhpur, respectively. After passing each other they take 4 hours 48 minutes and 3 hours 20 minutes to reach Jaipur and Jodhpur, respectively. If X is moving at 45 km/hr, the speed of Y is:
Option 1: 60 km/hr
Option 2: 58 km/hr
Option 3: 54 km/hr
Option 4: 64.8 km/hr
Correct Answer: 54 km/hr
Solution : We know, $\frac{\text{Speed of X}}{\text{Speed of Y}}=\sqrt{\frac{\text{Time taken by Y after crossing X}}{\text{Time taken by X after crossing Y}}}$ $⇒\frac{45}{\text{Speed of Y}}=\sqrt{\frac{\text{3 hour 20 min}}{\text{4 hour 48 min}}}=\sqrt{\frac{\text{200 min}}{\text{288 min}}}=\sqrt{\frac{100}{144}}$ $⇒\frac{45}{\text{Speed of Y}}=\frac{10}{12}$ $\therefore \text{Speed of Y}=54$ km/hr Hence, the correct answer is 54

Question : What powers the Earth's internal heat engine?
Option 1: Solar Energy
Option 2: Volcanoes
Option 3: Radioactive energy
Option 4: Tides
Correct Answer: Radioactive energy
Solution : The correct answer is Radioactive energy.
