Question

Find the values of the letters in each of the following and give reasons for the steps involved:

$3A$
$\underset{–}{+25}$
$\underset{–}{B2}$

• A. $B=6,A=7$
• B. $B=8,A=7$
• C. $B=6,A=2$
• D. None of these

Answer 1

Answer: (A)

$B=6,A=7$

$37$
$\underset{–}{+25}$
$\underset{–}{62}$
On studying
the addition in the one's column : from A + 5, we get '2' that is, a
number whose one's digit is 2. Thus, A should be 7, So, the puzzle can
be solved as shown in right side.
That is $B=6,A=7$
