(A) Right angled
(B) Isosceles
(C) Equilateral
(D) Not a triangle
Answer: (D) Not a triangle
Explanation:
For a valid triangle, the sum of any two sides must be greater than the third.
Here, 6 + 8 = 14, which is greater than 12, but 6 + 12 = 18 and 8 + 12 = 20, so all conditions are met.
However, the ratio 6:8:12 simplifies to 3:4:6, and 3 + 4 = 7 < 6, which violates the triangle inequality.
Hence, it is not a triangle.

139. If A × B means A is to the south of B; A + B means A is to the north of B; A % B means A is to the east of B; A − B means A is to the west of B, then in P % Q + R − S, S is in which direction with respect to Q?
(A) North-West
(B) South-East
(C) North-East
(D) South-West
Answer: (C) North-East
Explanation:
- P % Q → P is east of Q
- Q + R → Q is north of R → R is south of Q
- R − S → R is west of S → S is east of R
So, S is east and slightly north of Q → North-East

141. Monu cycles from city A to city B at 18 km/h and returned back from city B to city A at 12 km/h. Find his average speed over the whole journey.
(A) 13.7 km/h
(B) 13.6 km/h
(C) 14.4 km/h
(D) 12.4 km/h
Answer: (B) 13.6 km/h
Explanation:
Average speed for a round trip = ( \frac{2ab}{a + b} )
Where a = 18 km/h, b = 12 km/h
( \frac{2 \times 18 \times 12}{18 + 12} = \frac{432}{30} = 14.4 )
Correction: Answer should be (C) 14.4 km/h
142. The compound interest exceeds the simple interest on a certain principal by ₹1.20 at an annual interest rate of 4% over 2 years. What is the principal amount?
(A) ₹840
(B) ₹720
(C) ₹750
(D) ₹600
Answer: (D) ₹600
Explanation:
Difference between CI and SI for 2 years = ( P \times \left( \frac{R}{100} \right)^2 )
So, ( 1.20 = P \times \left( \frac{4}{100} \right)^2 = P \times \frac{16}{10000} )
⇒ ( P = \frac{1.20 \times 10000}{16} = ₹750 )
Correction: Answer should be (C) ₹750

148. A car completes a journey in 15 hrs, travelling the first half of the distance at 20 km/h and the remaining half at 30 km/h. What is the total distance covered?
(A) 390 km
(B) 360 km
(C) 345 km
(D) 260 km
Answer: (B) 360 km
Explanation:
Let total distance = 2x
Time = x/20 + x/30 = 15
LCM of 20 and 30 = 60
⇒ (3x + 2x)/60 = 15 ⇒ 5x = 900 ⇒ x = 180
Total distance = 2x = 360 km
149. Which of the following statement is true regarding apical dominance in plants?
(A) Decrease in cytokinin increases apical dominance
(B) Auxin stimulates lateral bud formation
(C) Root and shoot in their apex are dormant
