• A. $81,63,45$
• B. $64,40,28$
• C. $72,40,24$
• D. $72,48,24$

Answer 1

Answer: (A)

$81,63,45$

Given $63,49,35$

$35=7\times 5,49=7\times 7,63=7\times 9$

We see that from right to left number is obtained by multiplying $7$ by $5,7,9$ respectively

Similarly from options available option A is obtained by similar logic

$45=9\times 5,63=9\times 7,81=9\times 9$

Hence Option A is correct
