100 lakhs make a crore

Log boat:
- A log boat is a primitive type of boat that is made by hollowing out a log.
- It is propelled by paddling or rowing using oars or paddles.
- The speed of a log boat depends on the strength and speed of the person rowing it.
- It is generally a slow-moving boat due to its heavy and bulky nature.

Motor boat:
- A motor boat is a type of boat that is powered by an engine.
- It uses a propeller to move through the water and can achieve higher speeds compared to other types of boats.
- The speed of a motor boat depends on the power of the engine and the design of the boat.
- Motor boats can reach speeds of up to 60 miles per hour or more, depending on their size and horsepower.

Oar boat:
- An oar boat is a type of boat that is propelled by rowing using oars.
- Oars are long poles with blades at one end that are used to push against the water and propel the boat forward.
- The speed of an oar boat depends on the strength and endurance of the rower.
- It is generally slower than a motor boat but can still achieve decent speeds depending on the rower's ability.

All of these:
- The statement "All of these" suggests that all three types of boats mentioned (log boat, motor boat, and oar boat) have a speed of 4 km/hour.
- However, this statement is not accurate as the speed of these boats can vary significantly depending on various factors such as design, power source, and the strength of the person operating the boat.
- While it is possible for a log boat, motor boat, or oar boat to have a speed of 4 km/hour, it is not a fixed speed for all boats of these types.

Correct answer:
- The correct answer is option 'A' - log boat.
- Log boats, due to their heavy and bulky nature, are generally slower compared to motor boats and oar boats.
- They are not designed for speed but rather for stability and transportation over short distances.
- It is important to note that the speed of any type of boat can vary depending on various factors, and it is not accurate to generalize a fixed speed for all boats of a particular type.

Calculating the time taken to travel 50km:
To calculate the time it will take for the motor boat to travel 50km, we can use the formula:

Time = Distance/Speed
Given that the speed of the motor boat is 20km/h, we can substitute the values into the formula:

Time = 50km / 20km/h

Time = 2.5 hours
Therefore, it will take the motor boat 2.5 hours to travel 50km.

Correct answer:
b) 2 and 1/2 hours

Total Cost of Setting Up the Factory
The total cost to set up the fish-drying factory is 74,000. This is the amount required to ensure that the factory is fully operational and capable of processing fish.
Amount Saved
They have already saved 74,000. This means they have gathered enough funds to cover the total setup cost of the factory.
Calculating Additional Money Needed
To find out how much more money they need, we can subtract the amount they have saved from the total cost:
- Total Cost = 74,000
- Amount Saved = 74,000
When we perform the calculation:
- 74,000 (total cost) - 74,000 (amount saved) = 0
This means that they do not need any additional funds to set up the factory.
Conclusion
Since the calculation shows that they have exactly the amount needed, the correct answer is:
- 0 (They do not need any more money)
Thus, the correct answer is option A.

Understanding the Cost of Fresh Fish
To calculate the profit from selling dried fish, we first need to determine the cost of the fresh fish used to produce the dried fish.
- Cost of fresh fish:
6 kg of fresh fish is bought at 15 per kg.
Total cost = 6 kg * 15 = 90
Calculating the Revenue from Dried Fish
Next, we calculate the revenue generated from selling the dried fish.
- Weight of dried fish:
After drying, we end up with 2 kg of dried fish.
- Selling price:
The selling price is 70 per kg.
Total revenue = 2 kg * 70 = 140
Calculating the Profit
Profit is determined by subtracting the total cost from the total revenue.
- Profit calculation:
Profit = Total revenue - Total cost
Profit = 140 - 90 = 50
Conclusion
Thus, the profit made from selling the dried fish is 50. Therefore, the correct answer is option 'B'.

Understanding the Problem
To find out how much fish a motorboat can bring in 7 trips, we first need to know how much fish it can carry in one trip.
Fish Carried in One Trip
- The motorboat can carry 800 kg of fish in one trip.
Calculating Total Fish in 7 Trips
- To find the total fish brought in 7 trips, we multiply the amount of fish per trip by the number of trips:
- Total fish = Fish per trip × Number of trips
- Total fish = 800 kg × 7
Performing the Calculation
- Doing the multiplication:
- 800 kg × 7 = 5600 kg
Conclusion
- Therefore, in 7 trips, the motorboat will bring 5600 kg of fish.
Final Answer
- The correct answer is option A) 5,600 kg.
This calculation clearly shows how the total amount of fish is derived from the number of trips and the capacity of the boat per trip.

Loan Amount
Gracy took a loan of 4,000. This is the initial amount borrowed.
Monthly Payment
Gracy paid back 345 every month. This is her monthly repayment amount.
Duration of Loan
Gracy paid back the loan for one year. Since there are 12 months in a year, she made 12 payments.
Total Amount Paid
To find out how much she paid back in total, we need to multiply her monthly payment by the number of months:
- Monthly Payment: 345
- Number of Months: 12
So, the calculation is:
- Total Amount Paid = 345 * 12
Calculation
Now, let’s calculate it step-by-step:
- 345 * 12 = 4,140
Conclusion
In total, Gracy paid back 4,140. Therefore, the correct answer is option 'B'.
Understanding the Amount
- She borrowed 4,000 but paid back 4,140.
- The difference (4,140 - 4,000 = 140) reflects the interest or additional fees associated with the loan.
This breakdown helps in understanding not only the total repayment but also the implications of borrowing and repaying loans.

Understanding the Problem
To find out how far the motorboat will travel, we need to use the formula for distance, which is:
Distance = Speed × Time
In this case, we know the speed of the motorboat and the time it travels.
Given Data
- Speed of the motorboat: 20 km per hour
- Time traveled: 3.5 hours
Calculation Steps
1. Identify Speed and Time
- Speed = 20 km/h
- Time = 3.5 hours
2. Apply the Distance Formula
Using the formula:
Distance = Speed × Time
Distance = 20 km/h × 3.5 hours
3. Perform the Multiplication
- First, multiply 20 by 3.5:
20 × 3.5 = 70 km
Conclusion
The motorboat will travel a distance of 70 kilometers in 3.5 hours. Therefore, the correct answer is option 'C' (70 km).
Key Takeaway
- Always remember to multiply speed by time to find the distance traveled!
