Your answers are highlighted below.

Question 1 |

Two medians AD and BE of Î”ABC intersect at G at right angles. If AD= 9 cm and BE= 6 cm, then the length of BD, in cm, is

10 | |

6 | |

5 | |

3 |

Question 2 |

The length of rectangular plot is thrice its breadth. If the area of the rectangular plot is 6075 sq. metres, what is its length?

145 metres | |

130 metres | |

75 metres | |

None |

Question 2 Explanation:

Let the length be 3x m and thus the breadth = x m.

3x

=> x= 45 m.

Thus length = 45X3 = 135 m

3x

^{2}=6075=> x= 45 m.

Thus length = 45X3 = 135 m

Question 3 |

In Î”ABC, AD is the internal bisector of âˆ A, meeting the side BC at D. If BD= 5 cm, BC= 7.5 cm, then AB: AC is

2: 3 | |

1: 2 | |

4: 5 | |

3: 5 |

Question 4 |

A wall 3m Ã— 2.7m Ã— 0.2m of concrete weight 320 kg per cubic meter. What will be the total weight of the wall in kg.?

5184.0 | |

51.84 | |

518.4 | |

51840. |

Question 4 Explanation:

Volume of the wall = 3 x 2.7 x 0.2 = 1.62 cu m.

Total weight = 320 X 1.62 = 518.4 Kg.

Total weight = 320 X 1.62 = 518.4 Kg.

Question 5 |

If the circumcentre of a triangle lies outside it, then the triangle is

Equilateral | |

Acute angled | |

Right angled | |

Obtuse angled |

Question 5 Explanation:

If the circumcentre is outside the triangle, the triangle must be obtuse.
