$117+9,999=10,116$
$117+99,999=1,00,116$

• A. $117+99,999=1,00,116$
• B. $117+9,99,999=10,00,116$
• C. $117+99,999=1,01,116$
• D. $117+99,999=1101116$

Answer 1

The correct option is B $117+9,99,999=10,00,116$

$Now117+999=1116117+(1000-1)=1117-1=1116Now117+9999=10116117+(10000-1)=10117-1=10116Now117+99999=100116117+(100000-1)=100117-1=100116Now117+999999=1000116117+(1000000-1)=1000117-1=1000116$
