  • Question 1/5
    1 / -0.33
    In a mixture of 80 litres of a liquid and water, 25% of the mixture is the liquid. How much water should be added to the mixture so that the liquid becomes 20% of the mixture?
    Solutions
    liquid in 80 litres of mixture =

    And water in the mixtue = 80 – 20 = 60

    Let  litres of water is added in the mixture, so

  • Question 2/5
    1 / -0.33
    A vessel contains 20 litres of acid. 4 litres of acid is taken out of the vessel and replaced by the same quantity of water. Next 4 litres of the mixture are withdrawn, and again the vessel is filled with the same quantity of water. Then find the ratio of acid left in the vessel with the quantity of acid initially in the vessel is :
    Solutions

    Final quantity =

    C→ capacity of vessel

    x→ Quantity taken out at a time

    n→ No. of process

    Final Quantity

    =

    =

    =

    =

    =12.8 litres

    Required ratio

    =12.8 : 20

    = 128 : 200

    = 16 : 25

  • Question 3/5
    1 / -0.33
    Vessels P and Q contain mixture of milk and water in the ratio 3:2 and 9: 1 respectively. In what ratio should quantities of mixture be taken from P and Q to form a mixture in which milk to water is In the ratio 11:4 ?
    Solutions

    According to question         

    LCM (5,10,15) = 30

    Hence, Required Ratio = 5 : 4

  • Question 4/5
    1 / -0.33
    Alloy A contain 70% copper and rest is tin. Alloy B contain 84% copper, 10% tin & rest are impurities. In which ratio both alloys are mixed so that in new mixture % of tin will be 20% ?
    Solutions

     Alloy A contains 30% tin while Alloy B contains 10% of tin

    So Alloy A                     Alloy B

    1 : 1

    So, both alloys should mixed in 1:1 so that in new mixture % of tin will be 20%

  • Question 5/5
    1 / -0.33
    In a class of 100 students, the average weight is 30 kg. If the average weight of the girls is 24 kg and that of the boys is 32 kg, then what is the number of girls in the class?
    Solutions
    By alligation,

    So the number of girls will be =( 1/(1+3))*100 = 25
