Answer 2

✿AnSwer:

(a) 15 mL of alcohol and 100 mL of water is the correct answer.

━━━━━━━━━━━━━━━━━━━

In every 100 mL of alcohol solution, there is 15% of alcohol present in it

That is,

$\sf \: 15\% \: of \: the \: 100 \: ml : - \\ \sf \: = 100 \times \dfrac{15}{100} \\ \sf \: = 15 \: ml$

Alcohol present in 100 mL alcohol solution is 15 mL.

Also,

★ Water present in 100 mL alcohol solution =

= 100 - 15

= 85 mL

Hence, it is proved that 15 % actually means 15 mL of alcohol and 100 mL of water.
