सही विकल्प: D

[ 12¹/₃ + 4³/₁₅ का 1/3 ]/[ 8/9 × 3/2 + 5/2 × 3/5 ] ÷ [ 4/5 का 7/8 ( 1/4 ÷ 5/4 + 3/2 ) ]/[ 7/4 + 5/8 -1/8 ] = ?
⇒ ? = [ 37/3 + 63/15 × 1/3 ]/( 4/3 + 3/2 ) ÷ [ 4/5 ×7/8 ( 1/4 × 4/5 + 3/2 ) ]/( 14 + 5 - 1 )/8
⇒ ? = [ 37/3 + 21/15 ]/( 8 + 9 )/6 ÷ [ 4/5 ×7/8 ( 1/5 + 3/2 ) ]/18/8
⇒ ? = [ 206/15]/17/6 ÷ 7/10 ( 17/10 )/18/8
⇒ ? = 206/15 × 6/17 ÷ 119/100 × 8/18
⇒ ? = 412/85 ÷ 476/900 = 412/85 × 900/476 = 18540/2023
∴ ? = 18540/2023
