- From the table, 54 is the highest number of seeds collected by anyone. It is Indra who collected 54 seeds. So, Indra collected the most seeds.
- From the table, Sunil collected 38 seeds, and Vicky collected 42 seeds. So, Sunil will need 42 âˆ’ 38 = 4 more seeds to be equal to Vicky. Therefore, Sunil will collect 4 more seeds to be equal to Vicky.
- From the table, Radhika has collected 24 seeds. If she gets 6 more seeds, then she will have 24 + 6 = 30 seeds. Therefore, if Radhika gets 6 more seeds, she will have 30 seeds.
- From the table, Gauri, Vicky and Indra each have collected more than 40 seeds. Therefore, three children have more than 40 seeds.
- From the table, Gauri has collected 47 seeds. To have 50 seeds, she will need 50 â€“ 47 = 3 more seeds. Therefore, Gauri needs 3 more seeds to have 50.
- Two seeds more than 40 means, 40 + 2 = 42. From the table, Vicky has collected 42 seeds. Therefore, Sunil has 2 seeds less than 40 and Vicky has 2 seeds more than 40

Question 8 : Fill in the blanks:
Answer : Count in 10â€™s, write the following number by adding 10 to the last number.
10 | 100 + 10 = 110 | 310 | 710 |
---|---|---|---|
10 + 10 = 20 | 110 + 10 = 120 | 310 + 10 = 320 | 710 + 10 = 720 |
20 + 10 = 30 | 120 + 10 = 130 | 320 + 10 = 330 | 720 + 10 = 730 |
30 + 10 = 40 | 130 + 10 = 140 | 330 + 10 = 340 | 730 + 10 = 740 |
40 + 10 = 50 | 140 + 10 = 150 | 340 + 10 = 350 | 740 + 10 = 750 |
50 + 10 = 60 | 150 + 10 = 160 | 350 + 10 = 360 | 750 + 10 = 760 |
60 + 10 = 70 | 160 + 10 = 170 | 360 + 10 = 370 | 760 + 10 = 770 |
70 + 10 = 80 | 170 + 10 = 180 | 370 + 10 =380 | 770 + 10 = 780 |
80 + 10 = 90 | 180 + 10 = 190 | 380 + 10 = 390 | 780 + 10 = 790 |
90 + 10 = 100 | 190 + 10 = 200 | 390 + 10 = 400 | 790 + 10 = 800 |
The correct answer is:
