13. A man buys an article for ₹250 and sells it for ₹200. His loss percent is:
एक व्यक्ति ₹250 में वस्तु खरीदकर ₹200 में बेचता है। हानि प्रतिशत है:
A15%
B20%
C25%
D30%
Show answer
Answer: B. 20%
Loss = 50; Loss% = 50/250 × 100 = 20%.
हानि = 50; हानि% = 50/250 × 100 = 20%।
14. The average of first 10 natural numbers is:
पहली 10 प्राकृत संख्याओं का औसत है:
A5
B5.5
C6
D6.5
Show answer
Answer: B. 5.5
Sum = 55; Average = 55/10 = 5.5.
योग = 55; औसत = 55/10 = 5.5।
15. If x + 1/x = 3, then x² + 1/x² is:
यदि x + 1/x = 3 है, तो x² + 1/x² का मान है:
A5
B7
C9
D11
Show answer
Answer: B. 7
x² + 1/x² = (x + 1/x)² − 2 = 9 − 2 = 7.
x² + 1/x² = (x + 1/x)² − 2 = 9 − 2 = 7।
16. Two pipes fill a tank in 12 and 24 hours. Together they fill it in:
दो नल एक टंकी को 12 और 24 घंटे में भरते हैं। साथ मिलकर वे भरेंगे:
A6 hours6 घंटे
B8 hours8 घंटे
C9 hours9 घंटे
D10 hours10 घंटे
Show answer
Answer: B. 8 hours (8 घंटे)
1/12 + 1/24 = 3/24 = 1/8 → 8 hours.
1/12 + 1/24 = 3/24 = 1/8 → 8 घंटे।
17. The value of √1296 is:
√1296 का मान है:
A34
B36
C38
D42
Show answer
Answer: B. 36
36 × 36 = 1296, so √1296 = 36.
36 × 36 = 1296, इसलिए √1296 = 36।
18. A sum doubles itself in 8 years at simple interest. The rate is:
साधारण ब्याज पर कोई राशि 8 वर्ष में दोगुनी हो जाती है। दर क्या है?
A10%
B12.5%
C15%
D20%
Show answer
Answer: B. 12.5%
SI = P in 8 years → R = 100/8 = 12.5%.
8 वर्ष में ब्याज = मूलधन → दर = 100/8 = 12.5%।
19. The angles of a triangle are in ratio 1:2:3. The largest angle is:
एक त्रिभुज के कोण 1:2:3 के अनुपात में हैं। सबसे बड़ा कोण है:
A60°
B75°
C90°
D120°
Show answer
Answer: C. 90°
x + 2x + 3x = 180 → x = 30. Largest = 3×30 = 90°.
x + 2x + 3x = 180 → x = 30। सबसे बड़ा = 3×30 = 90°।
20. A boat goes 20 km downstream in 2 hours. If the stream is 2 km/h, the speed of the boat in still water is:
एक नाव धारा के साथ 20 किमी 2 घंटे में जाती है। यदि धारा 2 किमी/घं है, तो शांत जल में नाव की गति है:
A6 km/h6 किमी/घं
B8 km/h8 किमी/घं
C10 km/h10 किमी/घं
D12 km/h12 किमी/घं
Show answer
Answer: B. 8 km/h (8 किमी/घं)
Downstream speed = 20/2 = 10 km/h = boat + 2 → boat = 8 km/h.
धारा के साथ गति = 20/2 = 10 किमी/घं = नाव + 2 → नाव = 8 किमी/घं।
21. What is the value of 15% of 300 + 20% of 150?
300 का 15% + 150 का 20% का मान क्या है?
A65
B70
C75

24 और 36 का महत्तम समापवर्तक (HCF) है:
A6
B8
C12
D18
Show answer
Answer: C. 12
24 = 2³×3, 36 = 2²×3². HCF = 2²×3 = 12.
24 = 2³×3, 36 = 2²×3²। HCF = 2²×3 = 12।
23. A discount of 25% on marked price ₹800 gives selling price:
₹800 अंकित मूल्य पर 25% छूट देने से विक्रय मूल्य होगा:
A₹560
