NCERT MCQ Solutions for Class 5 Maths Mela Chapter 1 We the Travellers – I

“Boats were probably the first form of transport invented by humans, much before bullock carts!” People also built boats and ships to travel across lakes, rivers and seas, indicating their early importance in human travel and exploration.

“About a hundred years ago, there were far fewer vehicles than today.” At that time, common forms of transport included “animal-drawn carts, cars, and trains.” This shows a mix of traditional and early modern vehicles.

The table demonstrating place value relationships clearly states, “10 Thousands = Ten Thousand = 10,000.” This fundamental concept in the Indian place value system illustrates how numbers are grouped and named, building up from smaller units to larger ones.

Its shows “1,380 = 1 Thousand + 3 Hundreds + 8 Tens + 0 Ones.” This breakdown helps in understanding the place value of each digit within a four-digit number, a key concept for reading and writing large numbers.

“We use a comma to help us read large numbers easily.” This formatting convention is crucial in the Indian place value system for segmenting digits, making multi-digit numbers more comprehensible and preventing misinterpretations when reading them aloud.

“A cyclist can cover 15 km in one hour.” To find the distance covered in 4 hours at the same speed, we multiply 15 km/hour by 4 hours, which equals 60 km. This is a direct application of basic multiplication.

To find the total number of students, we add the number of girls and boys: 461 + 439 = 900. This sum represents the total population of students for whom vehicles might be needed for a trip.

The total number of students is 900. A minibus can carry 25 people. To find the number of minibuses needed, we divide the total students by the capacity of one minibus: 900 ÷ 25 = 36.

“A book has around 200 pages, and each page has about 50 words. The book therefore has about 10,000 words in all.” This calculation demonstrates how large numbers can be derived from smaller, contextual ones.

The puzzle states: “If the sheep and grass are left on the shore, the sheep will eat the grass.” Additionally, “if the sheep and lion are left on the shore, the lion will eat the sheep.” Both scenarios are impermissible.

Mira exclaims in the puzzle, “No matter which two numbers you choose, you will get 9 in the end.” This property of digit manipulation, when repeating the process of forming numbers and subtracting, consistently leads to the number 9.

It shows “783 = 700+80+3.” This demonstrates how a number can be broken down into the sum of its place values, representing hundreds, tens, and ones, for a clearer understanding of its composition.

The question asks “How many thousands are there in 7,934?” and the corresponding blank is for the answer. In the number 7,934, the digit in the thousands place is 7, indicating 7 thousands.

To find how many ₹10 notes are in ₹7,934, you consider the total amount and divide by 10. It provides the answer as 793, implying that 793 tens make up the majority of the amount. 

The story begins by stating, “Once upon a time, there was a king who was very fond of horses. He had 20 horses of the best breed.” This establishes the initial number of horses in the royal stable before any incidents occurred.

After one horse was stolen, the caretaker arranged the remaining horses such that the king “counted 5 horses along each side.” This clever arrangement misled the king into believing the full count of 20 horses was still present.

The king originally had 20 horses. After the thief stole one horse, the actual number of horses remaining was 20 − 1 = 19. The text then explicitly asks the reader to “Count the horses one by one and check!”

“The following night, the thief stole another horse from the stable. Now, only 18 horses remained.” This indicates a second theft, reducing the total number of horses in the stable to 18.

The caretaker stated, “We have 5 horses along each side and there are 4 sides. So there are a total of 20 horses, your majesty.” However, this method double-counts the corner horses, leading to an incorrect total of 20 when only 19 were present, as indicated by the subsequent question.

“2,350 is the nearest ten of 2,346.” It also notes that it would take “4 jumps to reach 2,350” from 2,346, illustrating the concept of rounding to the nearest ten.
