The ratio of areas of two squares A and B are 4:25. If the side of the square A is 6m. Then, what is the measure of the side of square B? |

A) 256m
B) 15m
C) 12m
D) 32m
^{2}Correct Answer :15m Explanation :area of square A= (6)²= 36 m² As given 36:x²:: 4:25 |

What is the measure of the base angle of an isosceles triangle, if its vertical angle is 70°? |

A) 110°
B) 55°
C) 90°
D) 70°
Correct Answer :55° Explanation :The sum of all the angles of a triangle must equal 180 degrees. the measure of each base angle x.then |

If 'x' units are added to the length of the radius of a circle, what is the number of units by which the circumference of the circle is increased? |

A) X B) 2π C) 2πX D) X Correct Answer :2πX Explanation :Let the radius of the circle be r . If the radius is increased by 'X' units, the new radius will be (r + X) . The new circumference will be 2 π(r + X) = 2 πr + 2 πX |

The sides of a triangle are 30, 40 and 50 cm. Then this triangle is a? |

A) right-angled triangles B) acute-angled triangle C) obtuse-angled triangle D) equilateral triangle Correct Answer :right-angled triangles Explanation :As per Therefore, the triangles that follow this rule will be right angled triangles. The triangle with sides 30, 40, 50 follows the Pythagorean theorem, so it is a right angle Also 30, 40 and 50 are multiples of 3, 4, and 5 which is a well known
Below the list examples of Pythagorean triples- |

A polygon has 44 diagonals, the number of its sides are? |

A) 9 B) 10 C) 11 D) 12 Correct Answer :11 Explanation :
Let the side is n. because there are n sides, we have to subtract n from total number of line formed by joining two adjacent vertices of polygon. number of diagonals = n=11 (n can not be negative) |

If the length and breadth of a rectangular plot were increased by 20 percent; then what would be the percent increase in the area of the plot? |

A) 20% B) 44% C) 26% D) 36% Correct Answer :44% Explanation :Let the length of rectangle be x and breadth be y According to The question New Area= 6x/5 × 6y/5 = 36*xy/25 Changes in area= 36*xy/25 - xy =xy* (36-25 / 25) =11*xy/25 % change = (11*xy / 25)*100 / xy = 44% area would be increase |

If the length of a certain rectangle is decreased by 4 cm and the width is increased by 3 cm, a square with the same area as the original rectangle would result. Find the perimeter of the original rectangle? |

A) 40 cm B) 50 cm C) 60 cm D) 30 cm Correct Answer :50 cm Explanation :Let x and y be the length and breadth respectively.
for a square, length = width Solving eq (i) & (ii) x= 16 and y = 9 |

If the ratio of areas of two square is 225:256, then the ratio of their perimeters is? |

A) 256:225 B) 225:256 C) 16:15 D) 15:16 Correct Answer :15:16 Explanation :Let the side of squares be x and y respectively. Then Ratio of their perimeters = 4x / 4y = x / y = 15 / 16 |

The circumference of the semi-circle is 180 cm. If the side of a square is 60% more than the diameter of the circle, what is the perimeter of the square? |

A) 368 cm B) 464 cm C) 486 cm D) 448 cm Correct Answer :448 cm Explanation :Given that circumference of semi circle is = 180 Diameter of this semi circle, D = 2*R Now, Side of the square = 160/100 D = 160/100 * 2R = 3.2*R Perimeter of square = 4 * Side of the square = 4*3.2*R = 448 |
