1. 'చదవడం' అనే పదం ఏ క్రియారూపానికి ఉదాహరణ?
A) లట్లకారం
B) కృత్ప్రత్యయం
C) భవిష్యత్ కాలం
D) వృత్తాంతం
సరైన సమాధానం:- B) కృత్ప్రత్యయం
ఎందుకంటే '-డం' అనే ప్రత్యయం 'చదువు' అనే ధాతువుకు చేరి క్రియ నుండి నామవాచకంగా మారిన పదం.
వివరణ:-
కృత్ప్రత్యయం:- ధాతువులకు ప్రత్యయాలు చేర్చి క్రియలను నామవాచకాలుగా లేదా విశేషణాలుగా మార్చడాన్ని కృత్ప్రత్యయం అంటారు.
చదవడం:- 'చదువు' (ధాతువు) + 'డం' (ప్రత్యయం) = 'చదవడం' (చదవడం అనే క్రియను సూచించే నామవాచకం).
2. "రత్నగర్భ" అనే పదం ఏ సమాసం?
A) తత్పురుష సమాసం
B) ద్వంద్వ సమాసం
C) బహువ్రీహి సమాసం
D) కర్మధారయ సమాసం
సరైన సమాధానం:- "రత్నగర్భ" అనే పదం "రత్నములు గర్భమున
గలది" (రత్నాలు గర్భంలో
కలిగినది) అని విగ్రహవాక్యం. ఈ
సమాసంలో పూర్వపదం
(రత్నము), ఉత్తరపదం (గర్భము)
రెండూ ప్రధానం కాకుండా, మరొక
పదం (భూమి/ధరిత్రి) ప్రధానంగా
ఉంటుంది. కాబట్టి, ఇది
బహువ్రీహి సమాసం.

3. In a dataset, if the Pearson’s correlation coefficient (r) is –0.87, what does this value indicate?
A) A strong positive relationship
B) A strong negative relationship
C) A weak relationship
D) No relationship
Correct Answer:-
B) A strong negative relationship
Explanation:-
The value of Pearson’s r always lies between –1 and +1:
+1 indicates a perfect positive relationship
0 indicates no linear relationship
–1 indicates a perfect negative relationship
So, –0.87 means:
*As one variable increases, the other decreases significantly
*This indicates a strong negative correlation
For example:-
If the number of study hours increases and stress levels decrease, it shows a negative correlation.
4. What is an example of qualitative data?
A) Height
B) Weight
C) Blood Group
D) Income

5. The average age of 5 students is 20 years. If one more student joins, the average becomes 21 years. What is the age of the new student?
A) 25
B) 26
C) 27
D) 30
Correct Answer:- B) 26
Explanation:-
The average age of 5 students = 20 years
So, the total age of 5 students = 5 × 20 = 100 years
When one new student joins, the average = 21 years (that means total 6 students)
Total age of 6 students = 6 × 21 = 126 years
Now, the age of the new student =
Total age of 6 students − Total age of 5 students
= 126 − 100
= 26 years
6. In a shop, 3 products have prices: ₹100, ₹200, ₹300.
A customer buys 3 items: the 1st product 2 times, the 2nd product 3 times, and the 3rd product 5 times.
What is the Weighted Average Price of the customer’s spending?
A) ₹200
B) ₹240
C) ₹230
D) ₹250
Correct Answer:- C) Rs. 230
Explanation:-
Total Spending
1st product = ₹100 × 2 = ₹200
2nd product = ₹200 × 3 = ₹600
3rd product = ₹300 × 5 = ₹1500
total spending= 200 + 600 + 1500 = ₹2300
Total Items = 2 + 3 + 5 = 10 items
Weighted Average Price=
total spending ÷ Total Items = 2300 ÷ 10 = ₹230

PHYSICS
1. If you double the frequency of a wave while keeping the speed constant, what happens to its wavelength?
ఒక తరంగం వేగం ఒకటే ఉండగా, frequency ని రెండింతలు పెంచితే, wavelength ఏమవుతుంది?
A) It doubles (రెండింతలు పెరుగుతుంది)
B) It halves (అరవుతుంది)
C) It stays the same (మారదు)
D) It becomes zero (సున్న అవుతుంది)
Correct Answer/సరైన సమాధానం:-
B) It halves (అరవుతుంది)
Explanation:-
Wave speed (v) = frequency (f) × wavelength (λ).
If speed is constant and frequency doubles, wavelength must decrease by half to maintain the equation.
తరంగ వేగం (v) = తరంగదైర్ఘ్యం (λ) × తరంగాల తీవ్రము (frequency, f)
వేగం స్థిరంగా ఉంటే, frequency రెండింతలు అయినప్పుడు, ఈ సమీకరణను సమతుల్యం చేయడానికి తరంగదైర్ఘ్యం అరవుతుంది.
2.Which of the following scientist was awarded the Nobel prize in physics for his discovery of the photoelectric effect?
A)Albert Einstein
B) Niels Bohr
C)Marie Curie
D)Werner Heisenberg
Correct Answer:- A)Albert Einstein
Explanation:-
Albert Einstein was awarded the Nobel Prize
in Physics in 1921 for his discovery of the
photoelectric effect. While he is most famous
for his theory of relativity, his work on the
photoelectric effect, which demonstrated the
particle nature of light, was
groundbreaking in quantum mechanics
and led to a better understanding of light as
both a wave and a particle.
3.Why can't we hear sound in
space?
*Sound needs a medium like air, water, or solids to travel.
* Space is a vacuum, it has no air.
*Without a medium, sound waves cannot travel.
*That's why space is always silent.

APTITUDE TEST
1. A shopkeeper marks an article 20% above cost price and allows a discount of 10% on the marked price. What is the profit percentage?
ఒక షాపు యజమాని ఒక వస్తువుపై కాస్ట్ ప్రైస్ కంటే 20% ఎక్కువగా మార్క్‌డ్ ప్రైస్ పెట్టి, ఆ మార్క్‌డ్ ప్రైస్‌పై 10% డిస్కౌంట్ ఇస్తాడు. అప్పుడు అతనికి వచ్చే ప్రాఫిట్ శాతం ఎంత?
A) 8%
B) 10%
C) 12%
D) 15%
Correct Answer/సరైన సమాధానం:-
A) 8%
Assume Cost Price (CP) = ₹100 (taking 100 makes percentage calculations easy).
Marked Price (MP) = 20% above cost price
MP = 100 + 20% of 100 = 100 + 20 = ₹120
Selling Price (SP) = 10% discount on MP
SP = 120 - 10% of 120 = 120 - 12 = ₹108
Profit = SP – CP
Profit = 108 - 100 = ₹8
Profit % = (Profit ÷ CP) × 100
Profit% = 8/100*100 = 8%
