    Solutions

    Explanation :

    1994 E = 12 L

    % P = (I – E)*100 / E

    50 = (I – 12)*100 / 12

    I = 6+12 = 18 L

    1995 E = 14L

    60 = (I – 14)*100 / 14

    I = 22.4L

    Total = 18+22.4 = 40.4L

    If the incomes of the B in 1992 and 1993 were in the ratio 3:4, Find the ratio of Expenditures of that company in these 2 years ?

    Solutions

    Explanation :

    Income => 1992:1993 = 3:4 = 30:40

    45 = (30-E)*100/E

    45E/100 = 30 – E

    9E/20 = 30 – E

    9E = 600 – 20E

    29E = 600

    E = 600/29……………1992

    50 = (40 – E)*100 / E

    50E/100 = 40 – E

    E = 2(40 – E)

    E = 80 – 2E

    3E = 80

    E = 80/3

    Ratio = (600/29) / (80/3) = 600*3 / 29*80

    = 1800/2320 = 180/232 = 45/58

     

  • Question 15/20
    1 / -0

    Direction (11-15) : Study the following information to answer the given questions.

    If the expenditure of A and B in 1991 were equal and total income of  A and B was
    Rs. 116L, what was the total expenditure of A and B in the same years ?

    Solutions

    Explanation :

    For A

    40 = (I – E)*100/E

    40E = (I – E)100

    2E = 5I – 5E

    5I = 7E

    I = 7/5 E

    For B

    50 = (116-I – E)*100/E

    E = 2(116 – I – E)

    E = 232 -2I – 2E

    2I = 232 – 3E

    I = (232 – 3E)/2

    7/5E = (-232 – 3E)/2

    14E = 1160  – 15E

    29E = 1160

    E = 1160/29 = 40

    2E = 80
