Question

Insert the missing number.

• A. $\frac{24}{45}$
• B. $\frac{23}{46}$
• C. $\frac{25}{44}$
• D. $\frac{25}{48}$

Answer 1

Answer: (C)

$\frac{25}{44}$

The numbers in the upper boxes have the following logic:

$23-1=22$

$22+2=24$

$24-3=21$

$21+4=25$

The numbers in the lower boxes have the following logic:

$46+1=47$

$47-2=45$

$45+3=48$

$48-4=44$

Hence, option C is correct.
