Hello Doston


Sociology admin here

Pata nahi Shekhar sir ko kya ho gaya hai, subah se notes hi banaye jaa rahe hain 🥲

Sir ki toh Kal ke Masterclass ke liye zoron shoron se prep chal rahi hai, aap bhi kar rahe hain ??

(it’s free if you’ve ever been a sleepy student. just drop in an email at sleepy.classes@gmail and we’ll send you the link… others can enrol on website)

We’ll cover the entire Sociology Paper 1 in one day tomorrow 🙏

Goodmorning everyone,

Today we start the CSAT series for UPSC 2027..

In this we will be alternating...PYQs of Maths, LR and English with one question a day

Today the question is an easy LR question

Try to solve half the question in your mind..before picking up the pen

Workshop aaj hai doston!

UPSC 2027 ki preparation start karni hai but samajh nahi aa raha kahan se shuru karein?

Join this session!

We'll talk about where to start, how to plan your GS preparation, beginner mistakes to avoid, and how to build the right foundation from Day 1.

Shekhar sir on FIRE🔥

Teaching Sociology since 11am!!🫡

Unprecedented efforts to GET TOP RANK from Sociology this year🙏🏼🙏🏼

​Given Equations

​A + B + C + D = 17 (1)
​A + C = 6 (2)
​P + Q + S + D = 15 (3)
​P + Q + R + B = 17 (4)

​P = R and Q = S

​Step 1

Find combined weight of B and D

Substitute eq (2) into eq (1)

(A + C) + B + D = 17
6 + B + D = 17
B + D = 11

​Step 2

Rewrite (3) and (4) using P and Q

Since P = R and Q = S

Eq (3) becomes

P + Q + Q + D = 15

P + 2Q + D = 15

Eq (4) becomes

P + Q + P + B = 17

2P + Q + B = 17

​Step 3

Solve for P + Q

Add the two new equations together

(P + 2Q + D) + (2P + Q + B) = 15 + 17

3P + 3Q + (B + D) = 32

​Substitute B + D = 11

3(P + Q) + 11 = 32

3(P + Q) = 21

P + Q = 7

​Now seeing options we can say that option B is correct

We don't lack the science to beat cancer

We lack the funding and delivery to save lives.

​𝟭. 𝗧𝗵𝗲 𝗗𝗮𝘁𝗮
• Scale: 1 in 5 affected; cases will double by 2050.
• The Divide: 5-year survival is >85% (rich nations) vs. <30% (poor nations).
• Core Issue: Not a lack of science, but a failure of funding & delivery mechanisms.

​𝟮. 𝗚𝗹𝗼𝗯𝗮𝗹 & 𝗜𝗻𝗱𝗶𝗮 𝗚𝗮𝗽𝘀
• Policy Deficit: 82% of nations have plans, but <40% include them under UHC.
• India's Screening Failure: <2% of eligible women screened for cervical cancer; <1% for breast cancer.
• HPV Vaccine Lag: Only 31% global uptake despite high policy inclusion.

​𝟯. 𝗦𝗼𝗰𝗶𝗼-𝗘𝗰𝗼𝗻𝗼𝗺𝗶𝗰 𝗜𝗺𝗽𝗮𝗰𝘁
• Financial Ruin: 45% of patients face extreme financial hardship.
• Abandonment: Up to 90% drop out of treatment due to a choice between "treatment and solvency."

​𝟰. 𝗪𝗮𝘆 𝗙𝗼𝗿𝘄𝗮𝗿𝗱
• Shift from Commitment to Capability.
• Institutionalize Mass Early Screening.
• Integrate oncology into UHC to reduce Out-of-Pocket Expenditure (OOPE).

Why do some mountain communities survive heavy monsoons while others face tragedy?

The Tech
​IIT Mandi: Sensors (tilt meters, accelerometers) flag ground movement.

​Forecasting: Blends satellite data, slope stability & local rain.
​
Bottlenecks
​Hyper-localized: Cannot predict adjacent, unmonitored slopes.
​Lead Times: Only 24-48 hrs due to rain forecast limits.

​Infrastructure
NW Himalayas, Manipur & Mizoram are highly vulnerable.

Sikkim is safer fewer roads keep slopes naturally stable.
​
2-Year Roadmap

Macro-identify high-frequency zones.

Micro-install sensors at high-risk sites.

Goodafternoon everyone..

Today is the Day 2 of our CSAT 2027 series..

We alternate LR, Quant and English questions daily.

We have a Quant-Data Interpretation PYQ today.

Try to solve this!

You are the DM.

A minister pressures you to inaugurate a new bridge today before the Model Code of Conduct kicks in.

However, your executive engineer verbally warns you that final load-testing is incomplete and poses a marginal risk.

X receives exactly 3 distinct coins from the set {1, 2, 5, 10, 20}.

Let's find all possible combinations for the total amount (m) and categorize them by whether they include the "5" coin.

​Combinations without a 5..

​1 + 2 + 10 = 13 (Prime and Sum of digits = 4)

​1 + 2 + 20 = 23 (Prime and Sum of digits = 5)

​1 + 10 + 20 = 31 (Prime and Sum of digits = 4)

​2 + 10 + 20 = 32 (Not Prime and Sum of digits = 5)

​Combinations WITH a 5..

​1 + 2 + 5 = 8 (Not Prime and Sum of digits = 8)

​1 + 5 + 10 = 16 (Not Prime and Sum of digits = 7)

​2 + 5 + 10 = 17 (Prime and Sum of digits = 8)

​1 + 5 + 20 = 26 (Not Prime and Sum of digits = 8)

​2 + 5 + 20 = 27 (Not Prime and Sum of digits = 9)

​5 + 10 + 20 = 35 (Not Prime and Sum of digits = 8)

​Now Let's Evaluate the Statements..

​Statement I:

"m is not a prime number."

Looking at our lists, non-prime totals occur both without a 5 (e.g., 32) and with a 5 (e.g., 8, 16).

Because we get mixed results.

Statement I is Not Sufficient.

​Statement II:

"The sum of the digits of m is greater than 5."

Every single combination without a 5 results in a digit sum of 5 or less.

Every combination with a 5 results in a digit sum of 7 or higher.

Therefore, if the sum of the digits is greater than 5, X absolutely must have received a 5 coin. Statement II is Sufficient.

Hence answer is Option A

There are a lot of coaching centers who are good at providing “value additions”

Such value additions make sense when we have already prepared our fundamentals and content so well that the “value additions” add a few extra marks on the base

But, students often fail to understand that it will always be fundamentals, the static part, the thorough current affairs, that get them through

Using the great philosopher Wittgenstein’s words that

“Raisins may be the best part of a cake, but a bag of raisins is not better than a cake”

Praying you do your basics the best and get through this exam at the earliest 😊
