A train leaves Mumbai at 10:00 AM and travels at a speed of 60 km/h. Another train leaves Delhi at 11:00 AM and travels towards Mumbai at a speed of 70 km/h. If the distance between Mumbai and Delhi is 1300 km, at what time will the two trains meet?

  1. 1:30 PM

  2. 2:30 PM

  3. 3:30 PM

  4. 4:30 PM


Correct Option: C
Explanation:

The relative speed of the two trains is 70 + 60 = 130 km/h. The time taken for the two trains to meet is 1300 / 130 = 10 hours. Since the second train leaves at 11:00 AM, the two trains will meet at 11:00 AM + 10 hours = 3:30 PM.

A shopkeeper sells a shirt for (\$20) and makes a profit of 20%. What was the cost price of the shirt?

  1. (\$16)

  2. (\$17)

  3. (\$18)

  4. (\$19)


Correct Option: A
Explanation:

Let the cost price of the shirt be (\$x). Then, the profit is (\$20 - \$x). Since the profit is 20% of the cost price, we have (\$20 - \$x) = 0.2 (\$x). Solving for (\$x), we get (\$x) = (\$16).

A rectangular garden has a length of 20 meters and a width of 15 meters. What is the area of the garden?

  1. 300 square meters

  2. 350 square meters

  3. 400 square meters

  4. 450 square meters


Correct Option: A
Explanation:

The area of the garden is (20 \times 15 = 300) square meters.

A water tank has a capacity of 1000 liters. If the tank is currently filled to 60% of its capacity, how many liters of water are in the tank?

  1. 400 liters

  2. 500 liters

  3. 600 liters

  4. 700 liters


Correct Option: C
Explanation:

60% of 1000 liters is (0.6 \times 1000 = 600) liters.

A train travels a distance of 300 kilometers in 5 hours. What is the average speed of the train?

  1. 50 km/h

  2. 60 km/h

  3. 70 km/h

  4. 80 km/h


Correct Option: B
Explanation:

The average speed of the train is (300 \div 5 = 60) km/h.

A shopkeeper sells a product for (\$10) and makes a profit of 25%. What was the cost price of the product?

  1. (\$7)

  2. (\$8)

  3. (\$9)

  4. (\$10)


Correct Option: B
Explanation:

Let the cost price of the product be (\$x). Then, the profit is (\$10 - \$x). Since the profit is 25% of the cost price, we have (\$10 - \$x) = 0.25 (\$x). Solving for (\$x), we get (\$x) = (\$8).

A rectangular room has a length of 12 meters and a width of 8 meters. What is the perimeter of the room?

  1. 40 meters

  2. 48 meters

  3. 56 meters

Correct Option: A
Explanation:

The perimeter of the room is (2 \times (12 + 8) = 40) meters.

A water tank has a capacity of 2000 liters. If the tank is currently filled to 75% of its capacity, how many liters of water are in the tank?

  1. 1200 liters

  2. 1300 liters

  3. 1400 liters

  4. 1500 liters


Correct Option: D
Explanation:

A train travels a distance of 400 kilometers in 6 hours. What is the average speed of the train?

  1. 60 km/h

  2. 70 km/h

  3. 80 km/h

  4. 90 km/h


Correct Option: A
Explanation:

The average speed of the train is (400 \div 6 = 60) km/h.

A shopkeeper sells a product for (\$12) and makes a profit of 30%. What was the cost price of the product?

  1. (\$8)

  2. (\$9)

  3. (\$10)

  4. (\$11)


Correct Option: B
Explanation:

Let the cost price of the product be (\$x). Then, the profit is (\$12 - \$x). Since the profit is 30% of the cost price, we have (\$12 - \$x) = 0.3 (\$x). Solving for (\$x), we get (\$x) = (\$9).

A shopkeeper sells a product for (\$15) and makes a profit of 35%. What was the cost price of the product?

  1. (\$10)

  2. (\$11)

  3. (\$12)

  4. (\$13)


Correct Option: B
Explanation:

Let the cost price of the product be (\$x). Then, the profit is (\$15 - \$x). Since the profit is 35% of the cost price, we have (\$15 - \$x) = 0.35 (\$x). Solving for (\$x), we get (\$x) = (\$11).
