    Let x be the quantity of solution one in mixture.

    so solution 2 would be (400-x) L

    according to ques.

    80% of x + 30% of (400-x) = 62% of 400

    i. e. 80*x/100 + 30 * (400-x) / 100 = 62*400/100

    => 80x - 30x = 62*400 - 30*400

    => 50x = 32*400

    x=256 L

    therefore 256L of solution one is required
