Correct answer: A. x and w are equal.x और w बराबर हैं।

Explanation

x = (3/4) × (6/5) = 9/10. y = 3 ÷ (4/30) = 22.5. z = (15/4) ÷ 6 = 5/8. For w, the bracket 4(5 ÷ 6) is read as a group: 3 ÷ (4 × 5/6) = 3 ÷ (10/3) = 9/10 (the same value as 3 ÷ 4 ÷ (5 ÷ 6)). So x = w = 9/10, and the answer is x and w are equal.x = (3/4) × (6/5) = 9/10। y = 3 ÷ (4/30) = 22.5। z = (15/4) ÷ 6 = 5/8। w में कोष्ठक 4(5 ÷ 6) को एक समूह मानने पर 3 ÷ (4 × 5/6) = 3 ÷ (10/3) = 9/10 (यही मान 3 ÷ 4 ÷ (5 ÷ 6) का भी है)। अतः x = w = 9/10 और उत्तर x और w बराबर हैं है।
