​𝗥𝗶𝘀𝗶𝗻𝗴 𝗘𝘅𝘁𝗿𝗲𝗺𝗲 𝗪𝗲𝗮𝘁𝗵𝗲𝗿 𝗥𝗶𝘀𝗸𝘀:
India faces mounting climate threats like heatwaves, cyclones, and flash floods, with hot days increasing and extreme rain events tripling over recent decades.

​𝗧𝗵𝗲 𝗟𝗶𝗺𝗶𝘁 𝗼𝗳 𝗘𝗮𝗿𝗹𝘆 𝗪𝗮𝗿𝗻𝗶𝗻𝗴𝘀:
While forecasting has improved, warnings only indicate danger without teaching people what immediate actions to take during an emergency.

​𝗠𝗮𝗻𝗱𝗮𝘁𝗼𝗿𝘆 𝗦𝗲𝗮𝘀𝗼𝗻𝗮𝗹 𝗗𝗿𝗶𝗹𝗹𝘀:
Every school, college, and workplace should conduct two drills annually one before heatwaves and another before the monsoon.

​𝗣𝗿𝗮𝗰𝘁𝗶𝗰𝗮𝗹 𝗗𝗶𝘀𝗮𝘀𝘁𝗲𝗿 𝗧𝗿𝗮𝗶𝗻𝗶𝗻𝗴:
Drills should focus on real-world actions, such as identifying cooled spaces for heatwaves, practicing evacuation routes, and avoiding moving floodwaters.

​𝗦𝗰𝗵𝗼𝗼𝗹-𝗟𝗲𝘃𝗲𝗹 𝗘𝗱𝘂𝗰𝗮𝘁𝗶𝗼𝗻:
Disaster management must become a practical part of primary education to teach children local hazards, safe routes, and basic first aid.

​𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝘁𝘆 𝗦𝗮𝗳𝗲𝘁𝘆 𝗣𝗼𝗶𝗻𝘁𝘀: Every panchayat and urban ward should designate an accessible local safety point equipped with water, first aid.

Day 14

CSAT PYQ Series

Today, we will be looking at a Maths question.

We alternate between RC, LR and Quant PYQs in this series.

Try to solve it.

Solutions will be provided later today.

​Step 1:

Write the equation for the successive changes.

An increase of k% means multiplying by (1 + k/100).

A decrease of k% means multiplying by (1 - k/100).

​q = p * (1 + k/100) * (1 - k/100) * (1 + k/100) * (1 - k/100)

​Step 2:

Group and simplify the terms.

Using the algebra rule (a + b)(a - b) = a^2 - b^2

We can simplify each increase/decrease pair:

(1 + k/100) * (1 - k/100) = 1 - (k^2 / 10000)

​Since 10000 is 10^4, we can rewrite this fraction as:
(10^4 - k^2) / 10^4

​Step 3:

Combine both pairs.
Because the increase/decrease cycle happens twice,
we multiply the simplified pair by itself:

q = p * [ (10^4 - k^2) / 10^4 ] * [ (10^4 - k^2) / 10^4 ]
​q = p * [ (10^4 - k^2)^2 / (10^4)^2 ]

​Step 4:

Rearrange the equation.
Multiply the denominators:

(10^4)^2 = 10^8
Substitute that back in:
q = p * [ (10^4 - k^2)^2 / 10^8 ]

​Multiply both sides by 10^8 to clear the fraction:

q * 10^8 = p(10^4 - k^2)^2

​Conclusion:

This matches option (a): p(10^4 - k^2)^2 = q * 10^8

​𝐋𝐨𝐜𝐚𝐥𝐢𝐳𝐞𝐝 𝐕𝐮𝐥𝐧𝐞𝐫𝐚𝐛𝐢𝐥𝐢𝐭𝐢𝐞𝐬:

Climate change impacts vary based on distinct local ecologies, landscapes, and societies rather than following a single global pattern.

​𝐋𝐢𝐦𝐢𝐭𝐬 𝐨𝐟 𝐓𝐫𝐚𝐝𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐅𝐥𝐨𝐨𝐝 & 𝐋𝐚𝐧𝐝𝐬𝐥𝐢𝐝𝐞 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭:

Embankments restrict natural river movement, while human interventions like deforestation, quarrying, and road construction on fragile hillsides intensify floods and landslides.

​𝐅𝐥𝐚𝐰𝐬 𝐢𝐧 𝐑𝐞𝐥𝐢𝐞𝐟-𝐂𝐞𝐧𝐭𝐫𝐢𝐜 𝐆𝐨𝐯𝐞𝐫𝐧𝐚𝐧𝐜𝐞:

Recurring disasters expose the failure of relying mostly on post-disaster relief and rehabilitation instead of reducing vulnerabilities beforehand.

​𝐆𝐨𝐯𝐞𝐫𝐧𝐚𝐧𝐜𝐞 𝐚𝐧𝐝 𝐑𝐢𝐬𝐤:

Disaster risk is shaped by governance, ecological stewardship, and social vulnerabilities just as much as it is by meteorology.

​𝐈𝐧𝐝𝐢𝐚'𝐬 𝐓𝐰𝐨𝐟𝐨𝐥𝐝 𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞:

India must build better systems to anticipate disasters while rethinking the governance of rivers, forests, mountains, and cities based on current ecological realities.
