Answer 1

Answer:

$Option \: \green {(B)} \:is \: correct$

Step-by-step explanation:

$Number \:of \: people \: who\: speak \:Tamil \\= n(Tm} = 28\%$

$Number \:of \: people \: who\: speak \: Telugu \\= n(T} = 7\%$

$Number \:of \: people \: who\: speak \:both \\= n(Tm n T} = 5\%$

$n(Tm U T) = n(Tm) + n(T) - n(Tm n T )\\</p><p>= 28 + 7 - 5\\= 35 - 5 \\= 30\%$

$Now , \: Number \:of \: people \: who\: speak\\neither\:Tamil \:speak\:nor \:Telugu\\= 100 - 30 \\= 70\%$

Therefore.,

$Option \: \green {(B)} \:is \: correct$
