Question 45Asked in CTET February 2026 Paper 2 Maths & Science, 7 Feb 2026

Diagonals PR and QS of a parallelogram PQRS intersect at point O. If OP = (x + y) cm, OQ = 20 cm, OR = 16 cm and OS = (y + 7) cm, then the value of (7x − y)…किसी समांतर-चतुर्भुज PQRS के विकर्ण PR और QS बिंदु O पर प्रतिच्छेद करते हैं। यदि OP = (x + y) cm, OQ = 20 cm, OR = 16 cm और OS = (y + 7) cm हैं, तो (7x − y)…

Diagonals PR and QS of a parallelogram PQRS intersect at point O. If OP = (x + y) cm, OQ = 20 cm, OR = 16 cm and OS = (y + 7) cm, then the value of (7x − y) (in cm) is :
किसी समांतर-चतुर्भुज PQRS के विकर्ण PR और QS बिंदु O पर प्रतिच्छेद करते हैं। यदि OP = (x + y) cm, OQ = 20 cm, OR = 16 cm और OS = (y + 7) cm हैं, तो (7x − y) का मान (cm में) है :

Correct answer: (B) 88

Explanation

Diagonals of a parallelogram bisect each other: y + 7 = OQ = 20 gives y = 13, and x + y = OR = 16 gives x = 3. So 7x − y = 21 − 13 = 8.समांतर चतुर्भुज के विकर्ण एक-दूसरे को समद्विभाजित करते हैं: y + 7 = OQ = 20 से y = 13, और x + y = OR = 16 से x = 3। इसलिए 7x − y = 21 − 13 = 8।
