Question 54Asked in CTET December 2024 Paper 2 Maths & Science, 14 Dec 2024

PQRS is a parallelogram in which PQ = (4x + 1) cm, QR = 26 cm, RS = 25 cm and PS = (3y − 1) cm. Then, the value of (3x + 2y) (in cm) is :PQRS एक समांतर चतुर्भुज है, जिसमें PQ = (4x + 1) cm, QR = 26 cm, RS = 25 cm और PS = (3y − 1) cm है। तब, (3x + 2y) का मान (cm में) है :

Show answerHide answer

Correct answer: (C) 3636

Explanation

Opposite sides are equal: 4x + 1 = RS = 25 gives x = 6; 3y − 1 = QR = 26 gives y = 9. So 3x + 2y = 18 + 18 = 36.सम्मुख भुजाएँ बराबर होती हैं: 4x + 1 = RS = 25 से x = 6; 3y − 1 = QR = 26 से y = 9। अतः 3x + 2y = 18 + 18 = 36।
