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? यदि किसी वृत्त की त्रिज्या की लंबाई में 'X' इकाइयाँ जोड़ी जाती हैं, तो वृत्त की परिधि मे कितनी इकाइयाँ बढ़ जाती है? |

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? एक त्रिभुज की भुजाएँ 30, 40 और 50 सेमी हैं। फिर यह त्रिभुज है? |

A) right-angled triangles /समकोण त्रिभुज B) acute-angled triangle /न्यून कोण त्रिभुज C) obtuse-angled triangle /अधिक कोण त्रिभुज D) equilateral triangle /समभुज त्रिभुज 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? एक बहुभुज में 44 विकर्ण है, तो उसकी भुजाओं की संख्या होगी? |

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? यदि एक आयताकार भूखंड की लंबाई और चौड़ाई में 20 प्रतिशत की वृद्धि हुई थी; तो फिर भूखंड के क्षेत्र में प्रतिशत वृद्धि क्या होगी? |

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? यदि एक निश्चित आयत की लंबाई 4 सेमी कम हो जाती है और चौड़ाई 3 सेमी बढ़ जाती है, तो मूल आयत के समान क्षेत्र के साथ एक वर्ग बनेगा। मूल आयत की परिधि ज्ञात कीजिए? |

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? यदि दो वर्ग के क्षेत्रों का अनुपात 225: 256 है, तो उनकी परिधि का अनुपात है? |

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? अर्ध-वृत्त की परिधि 180 सेमी है। यदि वर्ग की भुजा, अर्ध-वृत्त के व्यास से 60% अधिक है, तो वर्ग का परिमाप क्या है? |

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 |
