• B. $354$
• C. $606$
• D. $768$

Answer 1

The correct option is A $1,122$

For shop $A$,
$\text{number of mobile phones sold of price range}\$(500-600)=232$
$\text{number of mobiles phones sold of price range}\$(600-700)=122$

For shop $B$,
$\text{number of mobile phones sold of price range}\$(500-600)=374$
$\text{number of mobile phones sold of price range}\$(600-700)=394$

$\therefore \text{Total number of mobile phones sold of price range}\$(500-700)=232+122+374+394=1,122$

Hence, option (a) is correct.
