Question

$ALT$ stands for

• A. $467$
• B. $427$
• C. $497$
• D. $437$

Answer 1

The correct option is A $467$

$TX7$
$+XT7$
$-------$
$A7T$
$-------$
As
the first column is the sum of two 7s, i.e., $7+7=14$. So $T=4$ and
1 is carried over. Therefore, now $1+X+T=L=7$ and since
$T=4X=L-T-1=7-4-1=2$.
Thus, $A=T+X=4+2=6$.
$ALT=467$ (jumbled up)
