**NCERT Solutions for Class 6 Maths Chapter 11 Exercise 11.1**

**Ques. 1. Find the rule which gives the number of matchsticks required to make the following matchstick patterns. Use a variable to write the rule.**

**Sol.1.** **(a)** A pattern of letter T = 2n (as 2 matchsticks are used in one letter)

**(b)** A pattern of letter Z = 3n (as 3 matchsticks are used in one letter)

**(c)** A pattern of letter U = 3n (as 3 matchsticks are used in one letter)

**(d)** A pattern of letter V = 2n (as 2 matchsticks are used in one letter)

**(e)** A pattern of letter E = 5n (as 5 matchsticks are used in one letter)

**(f)** A pattern of letter S = 5n (as 5 matchsticks are used in one letter)

**(g)** A pattern of letter A = 6n (as 6 matchsticks are used in one letter)

**Ques. 2. We already know the rule for the pattern of letters L, C and F. Some of the letters from Q.1 (given above) give us the same rule as that given by L. Which are these? Why does this happen?**

**Sol.2.** The rule for the pattern of letter L = 2n (as 2 matchsticks are used in letter L)

From Q.1, (a) and (d), i.e., letters T and V, give the same rule as that given by L, i.e., 2n. This is because, 2 matchsticks are used in each of these letters.

**Ques. 3. Cadets are marching in a parade. There are 5 cadets in a row. What is the rule which gives the number of cadets, given the number of rows? (Use n for the number of rows.)**

**Sol.3.** No. of rows = n

No. of cadets in one row = 5

Hence, the no. of cadets in n rows = 5n

**Ques. 4. If there are 50 mangoes in a box, how will you write the total number of mangoes in terms of the number of boxes? (Use b for the number of boxes.)**

**Sol.4.** No. of boxes = b

No. of mangoes in a box = 50

Hence, total no. of mangoes in b boxes = 50b

**Ques. 5. The teacher distributes 5 pencils per student. Can you tell how many pencils are needed, given the number of students? (Use ‘s’ for the number of students.)**

**Sol.5.** No. of students = s

No. of pencils to be distributed per student = 5

Hence, total no. of pencils needed to be distributed among s students = 5s

**Ques. 6. A bird flies 1 kilometer in one minute. Can you express the distance covered by the ****bird in terms of its flying time in minutes? (Use ‘t’ for flying time in minutes.)**

**Sol.6. **Distance covered by the bird in 1 minute = 1 km

Flying time in minutes = t min

Distance covered by the bird in t minutes = speed x time = 1 x t = t km

**Ques. 7. Radha is drawing a dot Rangoli (a beautiful pattern of lines joining dots with chalk powder. She has 8 dots in a row. How many dots will her Rangoli have for r rows?**

**How many dots are there if there are 8 rows? If there are 10 rows?**

**Sol.7.** No. of dots in 1 row = 8

No. of rows = r

No. of dots in r rows = 8r

For no. of rows = 8,

No. of dots in 8 rows = 8 × 8 = 64 dots

For no. of rows = 10,

No. of dots in 10 rows = 8 × 10 = 80 dots

**Ques. 8. Leela is Radha’s younger sister. Leela is 4 years younger than Radha. Can you write Leela’s age in terms of Radha’s age? Take Radha’s age to be x years.**

**Sol.8. **Radha’s age = x years

Hence, Leela’s age = 4 years less than Radha’s age

= (x – 4) years

**Ques. 9. Mother has made laddus. She gives some laddus to guests and family members; still 5 laddus remain. If the number of laddus mother gave away is l, how many laddus did she make?**

**Sol.9.** No. of laddus given to guests and family members = *l
*No. of laddus remaining = 5

No. of laddus made by her =

*l*+ 5

**Ques. 10. Oranges are to be transferred from larger boxes into smaller boxes. When a large box is emptied, the oranges from it fill two smaller boxes and still 10 oranges remain outside. If the number of oranges in a small box are taken to be x, what is the number of oranges in the larger box?**

**Sol.10.** No. of oranges in 1 small box = x

No. of oranges in 2 small boxes = 2x

No. of oranges remaining outside = 10

Hence, the total no. of oranges in the large box = 2x + 10

**Ques. 11. (a) Look at the following matchstick pattern of squares. The squares are not separate. Two neighbouring squares have a common matchstick. Observe the patterns and find the rule that gives the number of matchsticks in terms of the number of squares. (Hint: If you remove the vertical stick at the end, you will get a pattern of Cs.)**

**(b) Figure gives a matchstick pattern of triangles. As in Exercise 11 (a) above, find the general rule that gives the number of matchsticks in terms of the number of triangles.**

**Sol. 11 **

**(a)** In given figure, if we remove 1 vertical matchstick from each figure, we get the pattern of Cs.

No. of matchsticks in a C = 3

No. of matchsticks in a pattern of Cs = 3x

No. of matchsticks in a square = 3 + 1

For no. of squares = x

No. of matchsticks = 3x + 1

**(b)** In given figure, if we remove 1 matchstick from each figure, we get the pattern of 2 matchsticks, forming a table of 2.

No. of matchsticks in a pattern so formed = 2x

No. of matchsticks in a triangle = 2 + 1

For no. of triangles = x

No. of matchsticks = 2x + 1

**Sol.4. **Radius of the circle = r

Diameter of the circle = AB

d = CA + CB

d = r + r

d = 2r

**Ques. 5. To find sum of three numbers 14, 27 and 13, we can have two ways:**

**(a) We may first add 14 and 27 to get 41 and then add 13 to it to get the total sum 54**

**(b) We may add 27 and 13 to get 40 and then add 14 to get the sum 54.**

**Thus, (14 + 27) + 13 = 14 + (27 + 13)**

**This can be done for any three numbers. This property is known as the associativity of addition of numbers. Express this property which we have already studied in the chapter on Whole Numbers, in a general way, by using variables a, b and c.**

**Sol.5. **By using variable a, b and c, the property of associativity of addition of numbers can be expressed as,

(a + b) + c = a + (b + c)
