Solution

The correct option is A 729
If you observe the options, all of them are perfect squares whose roots are, 27,26,25 and 24.
Consider option (a), 729. Root of 729=27, where A=2,C=7.
As per the condition B>A, so let B=3.
Thus, AC×BC=27×37=999. Thus, option (a) will be the required solution.

यदि आप विकल्पों को देखें, तो वे सभी पूर्ण वर्ग हैं, जिनके मूल 27,26,25 और 24 हैं।
विकल्प (a), 729 पर विचार करें। 729 का मूल =27, जहां A=2,C=7
शर्त के अनुसार B>A, तो माना कि B=3
अत: AC×BC=27×37=999 । अत: विकल्प (a) अभीष्ट हल होगा।
