    Let his salary = 100
    House Rent = 100 * 2/5 = 40
    Food = 100 * 3/10 = 30
    Conveyance = 100 * 1/8 = 12.5.
    Total Salary = 100
    Savings = 1400
    100 - 40 + 30 + 12.5 = 1400
    17.5 = 1400
    1 = 1400/17.5
    100 = (1400 * 100)/17.5 = 8000.
    Total Salary = 8000.
    Expenditure on food = 8000 * 3/10 = 2400.
    Expenditure on conveyance = 8000 * 1/8 = 1000.
