In what ratio should solution 1 & 2 be mixed to get a solution which contains water and milk in the ratio 3:7?

(1) Solution 1 contains water and milk in the ratio 1:9 and Solution 2 contains water and milk in the ratio 2:3
(2) The amount of milk in 100 gallons of solution 1 is 80 gallons more than that of water in the same solution. Further 50 gallons of solution 2 contains 10 gallons more milk than water

W1+w2=3

M1+M2=7

W1:M1=1:9

W2:M2=2:3

Suff
