Test: The Fish Tale - 2 - Class 5 MCQ

The correct numeral for three lakh twenty thousand fifteen is 3,20,015.

This is because "lakh" represents the number 100,000,

so three lakh is equivalent to 3 x 100,000 = 300,000.

Then, twenty thousand is represented by 20,000.

Finally, fifteen is represented by 15.

Therefore, the correct numeral is 3,20,015.

Explanation: 

-In 5043, the digit '5' is in the thousands place.

-To calculate place value: 
Place value = Digit x Value of the place
Place value of '5' = 5 x 1000 = 5000

- Therefore, the place value of '5' in the number 5043 is 5000.

The given expression is a sum of four numbers: 4,00,000, 2,000, 50, and 8. Adding these numbers together, we get 4,02,058.

The place value of '5' in '65,708' is 5,000. In the number '65,708', the digit '5' is in the thousands place, which represents a value of 5,000.

The cost of a king fish is Rs.120 per kg.
To find the cost of a king fish weighing five and a half kg, we need to multiply the weight (5.5 kg) by the cost per kg (Rs.120).
5.5 kg multiplied by Rs.120 equals Rs.660.
Therefore, the cost of a king fish weighing five and a half kg is Rs.660.

The type of boat that usually has a maximum speed of 4 km/hour is the Log boat.

- Log boats are made from hollowed-out logs and are meant for slow rivers and shallow waters.
- Motor boats can go much faster because they have engines.
- Oar boats can also go faster than 4 km/hour, depending on how many people are rowing and how strong they are.

So, the answer is Log boat.

The correct answer is Whale shark because it is the largest fish species in the world. While the blue whale is the largest animal overall, it is a mammal, not a fish. The king fish and star fish are much smaller in size compared to the whale shark.

Let's look at the options:

-A: 1,00,00,000
This number has 1 in the crore place, which is much smaller than the other options.

-B: 8,88,88,888
This number starts with 8 in the crore place. While it's large, it’s still less than the next option.

-C: 9,99,99,999
This number has 9 in the crore place and 9 in all the other places, making it the highest possible 8-digit number.

-D: 9,99,99,990
This number also starts with 9 in the crore place, but the last digit is 0, making it smaller than option C.

When we compare all the numbers, 9,99,99,999 has the highest value because it starts with 9 in the highest place value (crore) and has 9s in all other positions.

So, the answer is C: 9,99,99,999, which is the largest 8-digit number.

Explanation: 

1 crore is equal to 100 lakhs.
In terms of numbers:

• 1 lakh = 100,000
• 1 crore = 10,000,000 (which is 100 times 1 lakh)

Therefore, 100 lakhs make a crore.

The motor boat can go 20 km in one hour.

To calculate how long it will take to go 50 km, we can divide 50 by 20.

This gives us 2.5, which is equivalent to 2 and 1/2 hours.

Therefore, it will take the motor boat 2 and 1/2 hours to go 50 km.
