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

**Ans.** A and D. The number of matchsticks are required in each of them is 2.

**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)**

**Ans.** Let the number of rows = n

Number of cadets in a row = 5

Therefore,

total number of cadets in n rows = 5n

**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)**

**Ans.** Let number of boxes = b

Total number of mangoes in a box = 50

Therefore total number of mangoes in b boxes = 50b

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

**Ans.** Let number of students = s

Pencils distributed per student = 5

Therefore total number of pencils = number of students × pencils per students

= 5s

**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.)**

**Ans.** t Km

**7. Radha is drawing a dot Rangoli ( a beautiful 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?**

**Ans.** Number of rows = r

Number of dots = 9

Therefore Total Number of dots in r rows = number of dots ×number of rows

= 9×r = 9r

Total number of dots in 8 rows = 9×8 = 72

Total number of dots in 10 rows = 9×10 = 90

**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.**

**Ans.** Let Radha’s age be x years.

Leela is 4 years younger than Radha. Therefore Age of Leela = x – 4 years

**9. Mother had 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?**

**Ans.** Total numbers of Laddus = Laddus given away + Laddus remained

Number of laddus mother gave away = l

Number of laddus remained = 5

Therefore total number of laddus = l + 5

**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?**

**Ans.** Number of oranges in a small box = x

Number of oranges in larger box = 2 times the oranges of smaller box + 10

Therefore,

Total number of oranges in larger box = 2x + 10
