  6. Two gallons of a mixture of spirit and water contains 12% of water. They are added to 3 gallons of another mixture, containing 7% of water, again half of a gallon of water is added to the whole mixture. Find percentage of water in the resulting mixture.
    17(3/11)%
    11(3/10)%
    15(2/121%
    12(3/7)%
    10(3/13)%
    Option A
    Required percentage of water
    = (12/100 × 2 + 7/100 × 3 + 0.5)/ 5.5 × 100
    = 95/5.5 = 190/11 = 17(3/11)%

     

  7. A man bought 80 eggs at the rate of 24 rupees per dozen 10 eggs got broken and the remaining eggs he sold at 3.20 rupees per egg. If he had spent 16 rupees on other expenses, find his profit or loss percentage.

    22(3/11)%
    27(5/13)%
    27(3/11)%
    Option E
    Total CP of eggs = 80 × 2 + 16 = 176 rupees
    Total S.P. of remaining eggs = 70 × 3.20 = 224 rupees
    Profit/loss percentage = (224−176)/176 × 100
    = 4800/176 = 27(3/11)%

    Rs. 1150
    Option C
    Total interest = Rs. 6125 Rate = 6% and increasing by 0.5% every year.
    Let total Loan Amount = P P = (6125 × 100)/(6 × 1 + 6.5 × 1 + 7 × 1 + 7.5 × 1 + 8 × 1)
    = 612500/35
    = Rs. 1750

    Option
    Total = 3+4+5 = 12
    n(s) = 12c3 = 220
    n(e) = 3c1 * 4c1 * 5c1 = 60
    P = 60/220 = 3/11
