A ) -60 ✅
B ) 60
C ) -30
D ) 30
Explanation:
What is the product of-2,-3, and-10?
Trick: Count the negative signs!
Odd number of negatives → Negative answer Even number of negatives → Positive answer
(-2) × (-3) × (-10)
There are 3 negative signs (odd), so the answer is negative.
2 × 3 × 10 = 60
Answer: -60
A ) 30 minutes
B ) 26 minutes ✅
C ) 20 minutes
D ) 15 minutes
Explanation:
If a train travels 180 km at a speed of 60 km/h ,how much less time will it take to complete the same journey at a speed of 70 km/h?
Trick: Time saved = (Distance × Speed difference) ÷ Product of speeds
Distance = 180 km Speed difference = 70 − 60 = 10 km/h
Time saved = (180 × 10) ÷ (60 × 70) = 1800 ÷ 4200 = 3/7 hour
Convert to minutes: 3/7 × 60 = 25.71 minutes
Answer: Approximately 25 minutes 43 seconds less.=26min
A ) 54 km
B ) 265km ✅
C ) 364km
D ) 928km
Explanation:
A train covers 32 kilometers in 14.5 minutes .If it continues to travel at the same rate ,which of the following is closest to the distance it will travel in 2 hours?
Trick: Distance = (Given distance × Total time) ÷ Given time
2 hours = 120 minutes
Distance = (32 × 120) ÷ 14.5 = 3840 ÷ 14.5 ≈ 264.83 km
Answer: Approximately 265 km.
A ) 58cm²
B ) 52cm²
C ) 25cm²
D ) 56cm² ✅
Explanation:
If the perimeter of a sector of a circle of radius 6.5 cm is 29 cm, then itd area is__________.?
Trick: Area of a sector = ½ × Radius × (Perimeter − 2 × Radius)
Radius = 6.5 cm Perimeter = 29 cm
Arc length = 29 − (2 × 6.5) = 16 cm
Area = ½ × 6.5 × 16 = 52 cm²
Answer: 52 cm²
A ) 250
B ) 25 ✅
C ) 43.56
D ) 2.5
Explanation:
How many pieces of 13.2 cm can be cut from a 330 cm long rod:
Number of pieces = Total length ÷ Length of each piece
= 330 / 13.2 = 3300 / 132 = 25
Answer: 25 pieces
A ) 144 ✅
B ) 288
C ) 12
D ) 256
Explanation:
In how many ways 4 boys and 3 girls can be seated in a row so that they are alternate?
Trick: Since there is one more boy, the arrangement must be:
B G B G B G B
Arrange 4 boys = 4! = 24 ways Arrange 3 girls = 3! = 6 ways
Total ways = 4! × 3! = 24 × 6 = 144
Answer: 144 ways
