Q.4 On increasing the radius of circle by 1 cm, its area is increased by 44 cm2 .The original radius of the circle is -

एक वृत्त की त्रिज्या में 1 सेमी. की वृद्धि करने पर इसका क्षेत्रफल 44 सेमी.2 बढ़ जाता है। वृत्त की मूल त्रिज्या है
  1. 5.6 cm
  2. 6.5 cm
  3. 6 cm
  4. 9 cm
SOL :

Let the original radius be r cm

 = 44
  ⇒ 2π (2r +1)   = 44

  2. (N – 2)
  3. (N – 4)
  4. (2N + 1)
SOL :

Let the number of boys be 4x and the number of girls be x
 Total score = (5x )N
 Let the average score of girls be P
⇒ (4x) (N +1)+xP =(5x)N
⇒ 4xN + 4x + xP = 5x N
 x (N - 4) = xP
.˙. P = (N – 4)
