Question

Which number should replace ? to complete the series

$583:293::488:?$

• A. $291$
• B. $378$
• C. $487$
• D. $581$
• E. None of these

Answer 1

The correct option is B $378$

The sum of the digits of the first number is $2$ more than the sum of digits of the second number. In $488,$ we have $4+8+8=20$ which is $2$ more than the sum of the digits in the number $378.$
Hence, option (B) is the correct answer.
