Question

(a) 27% (b) 34% (C) 36% How much of 30 percent alcohol solution should be added to 75 litres of 21 percent alcohol solution to make it a 25 percent alcohol solution? (a) 60 litres (b) 50 litres (c) 54 litres (d) 66 litres of mill and water to their brim​

Answer 1

Answer:

60 litres

Step-by-step explanation:

$\frac{sol1}{sol2} = \frac{25 - 21}{30 - 25} = \frac{4}{5}$

w.k.t. solution 2 is 75 litres.

If 5 is 75 what is 4

$\frac{75}{5} \times 4 = 60$

60 litres of 30 percent alcohol is required.
