    What is the cost of tiling a rectangular piece of land 500 m long and 200 m wide at a rate of ₹ 8 per hundred sq m?
    Solutions
    Area of rectangular plot = Length×Breadth

    In a town, 40% of population is adult female and 10% are children. 70% of adult female population and 50% of adult male population is married. The percentage of unmarried population is:

    Solutions

    Let total population = 100 
    Adult Female = 40% of total population = 40% of 100 = 40
    Children = 10% of total population = 10% of 100 =10
    Adult male = Total Population − Adult Female − Children = 100 − 40 − 10 = 50 

    Married female = 70% of Adult Female = 70% of 40 = 28  
    Married male = 50% of Adult Male = 50% of 50 = 25
    Unmarried adult female = 40 − 28 = 12, Children = 10, Unmarried adult male = 50 − 25 = 25

    Total unmarried population = 47
