Q.4 The length of a room floor exceeds its breadth by 25 m. The area of the floor remains unaltered when the length is decreased by 10 m but the breadth is increased by 8 m. The area of the floor is 

कमरे की फर्श की लम्बाई फर्श की चौड़ाई से 25 मी. अधिक है। यदि फर्श की लम्बाई 10 मी. कम कर दी जाये और चौड़ाई 8 मी. बढ़ा दी जाये, तो फर्श का क्षेत्रफल अपरिवर्तित रहता है, फर्श का क्षेत्रफल है- 

  1. 5400 m.2
  2. 5600 m.2
  3. 4800 m.2
  4. 5100 m.2
  5. None of these


Solutions 4
Let the breadth of floor be b m.
Then, length of the floor be (b + 25)
Area = (b + 25) × b
According to the question,
(b + 15) (b + 8) = (b + 25) × b
b2 + 8b + 15b + 120 = b2 + 25b
2b = 120
b = 60 m.
l = b + 25 = 60 + 25 = 85 m.
Area of the floor = 85 × 60 = 5100 m.2

माना फर्श की चौड़ाई b मी. है |
तो, फर्श की लम्बाई (b + 25) होगी |
क्षेत्रफल = (b + 25) × b
प्रश्नानुसार,
(b + 15) (b + 8) = (b + 25) × b
b2 + 8b + 15b + 120 = b2 + 25b
2b = 120
b = 60 मी.
l = b + 25 = 60 + 25 = 85 मी.
फर्श का क्षेत्रफल = 85 × 60 = 5100 मी.2

Q.10. In each of the following questions, two equations are given. You have to solve them and give answer.

निम्नलिखित प्रश्नों में दो समीकरण (I) और (II) दिये गये है दोनों समीकरण हल कीजिए और उत्तर दीजिए- 

I. p2 + 16p + 63 = 0
II. q2 + 13q + 42 = 0 

  1. If p > q
  2. If p > q
  3. If p < q
  4. If p < q
  5. If p = q or relationship can not be established


Solutions 4 

I. p2 +16p + 63 = 0
   p2 + 9p + 7p + 63 = 0
   p(p + 9) + 7(p + 9) = 0
   (p + 9)(p + 7) = 0
    p = –9, p = –7
II. q2 +13q + 42 = 0
     q2 + 7q + 6q + 42 = 0
     q(q + 7) + 6(q + 7) = 0
     (q + 7)(q + 6) = 0
     q = –7, q = –6
Hence, q > p
