Question 33Asked in CTET July 2024 Paper 2 Maths & Science, 7 Jul 2024

PQRS is a parallelogram whose diagonals PR and QS intersect at a point O such that OP = (x + 7) cm, OQ = (x + y) cm, OR = 20 cm and OS = 16 cm. Then, value…PQRS एक समांतर चतुर्भुज है, जिसके विकर्ण PR और QS परस्पर बिंदु O पर प्रतिच्छेद करते हैं। यदि OP=(x+7) cm, OQ=(x+y) cm, OR=20 cm तथा OS=16 cm है, तो (7y+5)…

PQRS is a parallelogram whose diagonals PR and QS intersect at a point O such that OP = (x + 7) cm, OQ = (x + y) cm, OR = 20 cm and OS = 16 cm. Then, value of (7y + 5) (in cm) is :
PQRS एक समांतर चतुर्भुज है, जिसके विकर्ण PR और QS परस्पर बिंदु O पर प्रतिच्छेद करते हैं। यदि OP=(x+7) cm, OQ=(x+y) cm, OR=20 cm तथा OS=16 cm है, तो (7y+5) का (cm में) मान है :
  1. A2121
  2. B2323
  3. C2626
  4. D2828
Show answerHide answer

Correct answer: (C) 2626

Explanation

Diagonals of a parallelogram bisect each other: x + 7 = 20 gives x = 13; x + y = 16 gives y = 3. So 7y + 5 = 21 + 5 = 26.समांतर चतुर्भुज के विकर्ण एक-दूसरे को समद्विभाजित करते हैं: x + 7 = 20 से x = 13; x + y = 16 से y = 3। अतः 7y + 5 = 21 + 5 = 26।
