Option 1: 57
Option 2: 53
Option 3: 45
Option 4: 69
Correct Answer: 53
Solution : Given: 8, 17, ?, 197, 773, 3077
Add 4 times the previous difference to get the next term – 8 + 9 = 17; 17 + (9 × 4) = 17 + 36 = 53; 53 + (36 × 4) = 53 + 144 =
Question : If two concentric circles have radii of 5 cm and 3 cm, then the length of the chord of the larger circle that touches the smaller circle is:
Option 1: 6 cm
Option 2: 7 cm
Option 3: 10 cm
Option 4: 8 cm
Correct Answer: 8 cm
Solution : Let O be the centre of the concentric circle of radii 5 cm and 3 cm, respectively. Let PQ be a chord of the larger circle that touches the smaller circle at point M. OM $\perp$ PQ In $\triangle \mathrm{OMP}$, $\mathrm{OP^2=OM^2+PM^2}$ ⇒ $\mathrm{5^2=3^2+PM^2}$ ⇒

Question : $\triangle BAC\sim \triangle PQR$. The area of $\triangle BAC$ and $\triangle PQR$ is 25 cm2 and 36 cm2 respectively. If BA = 4 cm, then what is the length of PQ?
Option 1: 5.8 cm
Option 2: 4.2 cm
Option 3: 4.8 cm
Option 4: 5 cm
Correct Answer: 4.8 cm
Solution : Given: $\triangle BAC\sim \triangle PQR$. The area of $\triangle BAC$ and $\triangle PQR$ is 25 cm2 and 36 cm2 respectively. BA = 4 cm A similar triangle's area is proportional to the squares of the respective sides. Let PQ be $x$ cm.

Question : Comprehension: Read the given passage and answer the questions that follow. Climate policy must now put health at the centre and promote climate change mitigation policies that bring health benefits simultaneously. Health-focused climate policy would help bring about a planet that has cleaner air, more abundant and safer fresh water and food, more effective and fairer health and social protection systems, and, as a result, healthier people. Investments in clean energy will yield health gains that repay those investments twice over. There are proven interventions able to reduce emissions of short-lived climate pollutants, for instance, applying higher standards for vehicle emissions, which have been calculated to save approximately 2.4 million lives per year, through improved air quality and reduce global warming by about 0.5°C by 2050. The cost of renewable sources of energy has decreased significantly in the last few years, and solar energy is now cheaper than coal or gas in most major economies. Question: Which of the following most accurately states the central idea of the passage?
Option 1: Greenhouse gases
Option 2: Pollution
Option 3: Climate policy for health
Option 4: Fossil fuels
Correct Answer: Climate policy for health
Solution : The answer is the third option.
Explanation: The central idea of the passage is that climate policy should prioritise health, and by doing so, it can bring about multiple benefits such as cleaner air, safer water and food, more effective health and
