Detailed Explanation & Answer
A. 4.3 x 100 / 13.8 = 31.16
B. 3.8 x 100 / 12.7 = 29.92
C. 5.7 x 100 / 14.9 = 38.26
D. 4.7 x 100 / 14.1 = 33.33

So, the correct order is C, D, A, B.
ए. 4.3 x 100 / 13.8 = 31.16
बी. 3.8 x 100 / 12.7 = 29.92
सी. 5.7 x 100 / 14.9 = 38.26
डी. 4.7 x 100 / 14.1 = 33.33

तो, सही क्रम C, D, A, B है।
