    A man sells his typewriter at 5% loss. If he sells it for Rs.80 more, he will gain 5%. The cost price of the type writer is
    ARs.1600
    BRs.1200
    CRs.1000
    DRs.800

    Answer: (1) Rs.1600

    Explanation:-
    L the cost price of a type writer is Rs.X
    Loss = 5 %

    Then, the selling price of typewriter = \(X \times \frac{95}{100}\)
    = \(\frac{19 X}{20}\)

    Gain = 5 %
    Then the selling price = \(X \times \frac{105}{100}\)
    = \(\frac{21 X }{ 20}\)

    Then,

     \(\frac{21 X }{ 20} – \frac{19 X}{20} = 80\)
    \(\frac{( 21 X –  20 X ) }{ 20} = 80\)
    \(X = 80 \times 20\)
    \(X = Rs.1600\)

    Then, the cost price of a typewriter is Rs.1600

    Hence, the answer is (1) Rs.1600.

    \(\frac{105x}{100}-\frac{95x}{100}\)=80

    \(\frac{10x}{100}\)=80

    \(X=80×\frac{100}{10}\)

    X=800 correct answer

    CP=X

    LOSS =5%

    GAIN=5%

    SP=CP(100-LOSS)/100

    95×/100=19×/20

    SP=CP (100 +PROFIT)/100= X(100+5)/100= 105X/100 = 21X/100 

    21X/20-19X/20=80

    X=80×20=1600
