$50 %$ $50 %$ of $s = 6$ $s = 6$ .

$r = 30$ $r = 30$
So,
$30 %$ $30%$ of $r = 30 \times \frac{30}{100} = 9$ $r = 30 xx 30/100 = 9$

This is given to be equal to 75% of s,

$75 % o f s = 9$ $75 % of s = 9$

$therefore sxx 75/100 =9$

$=> s = 900/75 = 12$

Asked: what is 50% of s if r=30?

$therefore 50% of s = 50/100 xx 12 =6$

Answer: $6$
