Answer :

From the given picture, note down the number of Imli seeds collected by Radhika, Gauri, Vicky, Indra, and Sunil. As shown in the table,

Names |
Number of Imli seeds collected |
---|---|

Radhika | 24 |

Gauri | 47 |

Vicky | 42 |

Indra | 54 |

Sunil | 38 |

- 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 − 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 – 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

- From the table, A.P.J. has scored 128 runs, and V.V.S. has scored 127 runs. Also, A.S. has scored 100 runs, and C.K. has scored 99 runs. Therefore, A.P.J. and V.V.S. have a difference of just 1 run between them. A.S. and C.K. have a difference of just 1 run between them.
- One and a half century means, 100 + 50 =150. So, 2 more than one and half century mean, 150 + 2 =152. From the table, K.S.P. has scored 152 runs. Therefore, K.S.P. scored 2 more than one and a half century.

Question 4 :

Fill in the blanks:

Answer :

Count in 10’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:
