Multiple Choice Questions

 (i) In the given map, a 1cm square grid represents 50km. What is the approximate distance between Jaunpur and Chapra?

(a) 250 km
(b) 450 km
(c) 350 km
(d) 150 km

Ans:  (a) 250 km
To calculate the distance between Jaunpur and Chapra, we followed these steps:

• Grid Measurement: The map is divided into 1 cm grid squares, and the scale tells us that each 1 cm on the map equals 50 kilometers on the ground.
• Estimate the Distance: By counting the number of grid squares between Jaunpur and Chapra, the distance is estimated to be around 5 cm.
• Convert to Real Distance: Since each centimeter on the map represents 50 kilometers, we multiply the 5 cm by 50 kilometers:

                           5 cm × 50 km/cm = 250 km

Therefore, the approximate distance between Jaunpur and Chapra is 250 km.

(ii) There is a pentagon drawn on a 1 cm square grid. If Mohan is asked to draw the same picture on a 2cm grid. The side of the square is made two times bigger. Does the area of square grids also become two times bigger?

(a) Yes, becomes two times bigger

(b) No, it becomes 4 times bigger 

(c) No, it becomes three times bigger

(d) No, it remains the same

Ans: (b) No, it becomes 4 times bigger 
The area of a square is calculated using the formula: Area = side × side.

1. Original Grid (1 cm):
   • Area = 1×1=11cm×1cm=1 square cm
2. New Grid (2 cm):
   • Area = 2×2=4 cm

When the side of the square becomes two times bigger, the area becomes four times bigger, not two times. Therefore, the correct answer is (b) No, it becomes 4 times bigger.

c) If the tiger wants to catch the deer, in which direction he should be making the jump?

(a) North

(b) South

(c) East

(d) West

Ans: (b) South
Based on the image and the compass directions provided, the tiger is positioned to the north of the deer. If the tiger wants to catch the deer, it should jump south.

So, Option b is correct.

Answer the following Questions

(i) 

Ans:   1. The Dog is located south of the Horse.

              2. The Cat is located southeast of the Horse.

              3. The Cow is located north of the Cat.

              4. The Horse is located northwest of the Cat.

              5. The Dog is located west of the Cat.

              6. The Cow is located east of the Horse.

              7. The Dog is located southwest of the Cow.

              8. The Cat is located south of the Cow.

(ii) Find out the scale used to draw the map using the distance information given.
Places – From Bengaluru to Lucknow
Actual distance – 1855 Km 
Distance on map – 5.3 cm
Ans: Actual distance =1855 km
Distance on map =5.3 cm
1 cm = 1855 km / 5.3 
= 1855km / 1 x 10/53 
= 18550 km/53 
∴ 1 cm = 350 km

(iii) Height of a building is 9 m and this building is represented by 9 cm on a map. What is the scale used for the map?
Ans: Given: The height of the building is 9m.
9m is represented by 9cm on the map.
We know that 1m = 100cm
therefore,
9m : 9cm ⇒ 900cm : 9cm
Scale used ⇒ 100:1

(iv) If actual distance between two places A and B is 110 km and it is represented on a map by 25 mm. Then the scale used is _____.
Ans: We know that
Scale of map = Size drawn on map / Actual size  = 25mm / 110km
25mm / 110000000mm
1/440000
So, If actual distance between two places A and B is 110 km and it is represented on a map by 25 mm. Then the scale used is 1 : 4400000

Answer the Following 

Q1: In a sports day event, students are lined up in rows of 6, 9, or 18. What is the smallest number of students that can be arranged in this way?

Sol: To determine the smallest number of students that can be arranged in rows of 6, 9, or 18, we need to calculate the Least Common Multiple (LCM) of the numbers 6, 9, and 18.
Prime factors:

• 6 = 2 × 3
• 9 = 3 × 3
• 18 = 2 × 3 × 3

Common factors and multiplication:

• Common factors = 2, 3 × 3
• Multiply all common factors: 2 × 3 × 3 = 18

Therefore, the smallest number of students is 18.

Q2: A baker has cookies that he wants to pack in boxes of 7, 14, or 21 cookies. What is the least number of cookies he needs to ensure there are no cookies left out?

Sol: To ensure no cookies are left out when packed in boxes of 7, 14, or 21, we find the LCM of these numbers.
Prime factors:

• 7 = 7
• 14 = 2 × 7
• 21 = 3 × 7

Common factors and multiplication:

The LCM takes the highest powers of all prime numbers involved: 2 × 3 × 7 = 42

Therefore, the baker needs at least 42 cookies.

Q3: At a community picnic, the organizers want to divide the attendees into groups of 4, 6, or 8 evenly. What is the minimum number of attendees needed?

Sol: To find the minimum number of attendees that can be divided evenly into groups of 4, 6, or 8, we calculate the LCM of these numbers.
Prime factors:

• 4 = 2 × 2
• 6 = 2 × 3
• 8 = 2 × 2 × 2

Common factors and multiplication:

Use the highest powers: 2³ and 3¹ → LCM = 8 × 3 = 24

Therefore, at least 24 attendees are needed.

Q4: A classroom has students who need to be arranged in rows of 10, 20, or 25 for a group photo. What is the least number of students that should be present?

Sol: To find the least number of students that can be arranged in rows of 10, 20, or 25, we look for the LCM.
Prime factors:

• 10 = 2 × 5
• 20 = 2 × 2 × 5
• 25 = 5 × 5

Common factors and multiplication:

Highest powers: 2² (from 20), 5² (from 25)
 →  LCM = 100

Therefore, at least 100 students should be present.

Q5: A musical concert is organized where the audience must be seated in sections of 15, 30, or 45. How many minimum seats should be available?

Sol: To find the minimum number of seats, calculate the LCM of 15, 30, and 45.
Prime factors:

• 15 = 3 × 5
• 30 = 2 × 3 × 5
• 45 = 3 × 3 × 5

Common factors and multiplication:

Highest powers of all primes: 2¹, 3², 5¹ → LCM = 90

Therefore, at least 90 seats should be available. These solutions use the factorization method to find the LCM, ensuring that students can understand the process through basic multiplication of common prime factors.

Q3: Find the area of the rectangle, whose:
(i) length = 5 m 8 cm, breadth = 3 m 75 cm
Ans: First convert to cm:

• 5 m 8 cm = 500 + 8 = 508 cm
• 3 m 75 cm = 300 + 75 = 375 cm

Now, Area = 508 × 375 = 1,90,500 cm²
