## NCERT Solutions for Class 6 Maths Chapter 11 Algebra Ex 11.1

**NCERT TEXTBOOK EXERCISES**

**Question 1. Find the rule which gives the number of matchsticks required to make the following matchstick patterns. Use a variable to write the rule.(a)** A pattern of letter T as

**(b)**A pattern of letter Z as

**(c)**A pattern of letter U as

**(d)**A pattern of letter V as

**(e)**A pattern of letter E as

**(f)**A pattern of letter S as

**(g)**A pattern of letter A as

**Solution.**

**(a)** Number of matchsticks required = 2n**(b)** Number of matchsticks required = 3n**(c)** Number of matchsticks required = 3n**(d)** Number of matchsticks required = 2n**(e)** Number of matchsticks required = 5n**(f)** Number of matchsticks required = 5n**(g)** Number of matchsticks required = 6

**Question 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?**

**Solution.**

These letters are T and V. This happens since the number>of matchsticks require,d in each of them is 2.

**Question 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.)**

**Solution.**

The number of cadets = 5n.

**Question 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.)**

**Solution.**

Total number of mangoes = 50b.

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

**Solution.**

Number of pencils needed = 5s

**Question 6. A bird flies 1 kilometer in one minute. Can you express the distance covered by the bird in tertns of its flying time in minutes? (Use t for flying time in minutes.)**

**Solution.**

Yes! / kilometers

The bird flies in one minute = 1 kilometer

The bird flies in / minutes = 1 x t kilometers

= kilometers

**Question 7. Radha is drawing a dot Rangoli (a beautified pattern of lines joining dots with chalk powder. She has 9 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?**

**Solution.**

âˆµ Number of dots in 1 row = 9

âˆ´ Number of dots in r rows = 9 x r=9r

Number of dots in 8 rows = 9 x 8 = 72

Number of dots in 10 row = 9 x 10 = 90

**Question 8. Leela is Radhaâ€™s younger sister. Leela is 4 years younger than Radha. Can you write Leelaâ€™s age in terms of Radhaâ€™s age? Take Radhaâ€™s age to be x years.**

**Solution.**

Yes! we can write Leelaâ€™s age in terms of Radhaâ€™s age.

Age of Radha = x years

âˆµ Leela is 4 years younger than Radha.

âˆ´ Age of Leela = (x â€“ 4) years

**Question 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?**

**Solution.**

Number of laddus given away to guests and family members = l

Number of laddus remained = 5

âˆ´ Number of laddus she made = 1 + 5

**Question 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 is taken to be x, what is the number of oranges in the larger box?**

**Solution.**

Let the number of oranges in a smaller box box

âˆ´ Number of oranges in two smaller boxes = 2x

Number of oranges remained outside = 10

âˆ´ Number of oranges in the larger box = 2x+ 10

**Question 11.**

**(a)** Look at the following matchstick pattern of squares (figure). The squares are not separate. Two neighboring squares have a common matchstick. Observe the pattern 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. Av in Exercise 11(a) above, find the general rule that gives the number of matchsticks in terms of the number of triangles.

**Solution.**

**(a)**

**Rule:** Number of matchsticks required = 3x + I

where x is the number of squares.

**(b)**

**Rule:** Number of matchsticks required = 2x + 1,

where x is the number of triangles.
