    Question

    There are two containers having equal quantities of

    mixtures of two chemical types A and B. The 1st container contains 30% of type A chemical whereas the 2nd container contains 60% of type B chemical. If the mixtures from both the containers are mixed together, then find the percent of the type A chemical in the resultant mixture.
    A 25% Correct Answer Incorrect Answer
    B 29% Correct Answer Incorrect Answer
    C 34% Correct Answer Incorrect Answer
    D 35% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the mixture in each container be 100 litres. Quantity of type A chemical in 1st container = 100 × 30% = 30 litres. Quantity of type B chemical in 2nd container = 100 × 60% = 60 litres. Quantity of type A chemical in 2nd container = 100 – 60 = 40 litres. Quantity of final mixture = 100 + 100 = 200 litres. Quantity of type A chemical in final mixture = 30 + 40 = 70 litres. Percent of Type A chemical in final mixture = 70/200 × 100 = 35%.
