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

(i) A pattern of letter T as T

(ii) A pattern of letter V as V

(iii) A pattern of letter Z as Z

(iv) A pattern of letter U as U

(v) A pattern of letter F as F

(vi) A pattern of letter S as S

Solution:

(i) Number of matchsticks required = 2n

(ii) Number of matchsticks required = 2n

(iii) Number of matchsticks required = 3n

(iv) Number of matchsticks required = 3n

(v) Number of matchsticks required = 4n

(vi) Number of matchsticks required = 5n

2. If there are 24 mangoes in a box, how will you write the number of mangoes in terms of the number of boxes? (Use b for the number of boxes.)
Solution:

Total number of mangoes = 24b

3. Anuradha is drawing a dot Rangoli (a beautiful pattern of lines joining dots). 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 12 rows?
Solution:

Given:

Number of dots in 1 row = 8

Number of dots in â€˜râ€™ rows = 8 Ã— r = 8r

Number of dots in 12 rows = 12 Ã— 8 = 96

4. Anu and Meenu are sisters. Anu is 5 years younger than Meenu. Can you write Anuâ€™s age in terms of Meenuâ€™s age? Take Meenuâ€™s age as x years.
Solution:

Yes, we can write Anuâ€™s age in terms of Meenuâ€™s age.

We know that age of Meenu = x years

It is given that Anu is 5years younger than Meenu.

So, age of Anu = (x – 5) years

5. Oranges are to be transferred from larger boxes to smaller boxes. When a larger box is emptied, the oranges from it fill 3 smaller boxes and still 7 oranges are left. If the number of oranges in a small box is taken to be x, then what is the number of oranges in the larger box?
Solution:

Let us consider number of oranges in a smaller box be â€˜xâ€™.

So, number of oranges in 3 smaller boxes = 3x

Number of oranges remained outside = 7

So, number of oranges in the larger box = 3x + 7

6. Harshaâ€™s score in Mathematics is 15 more than three-fourth of her score in Science. If she scores x marks in Science, find her score in Mathematics?
Solution:

Let us consider the score of Science be â€˜xâ€™.

It is given that Harshaâ€™s score in Mathematics is = Â¾ th of x + 15

So, Harshaâ€™s score in Mathematics is Â¾ x + 15
