  • Question 2/10
    1 / -0.25
    The sum of five consecutive even numbers A, B, C, D and E is 130. What is the product of A and E ?
    Solutions
    Let and A = x, B = x + 2, C = x + 4, D = x + 6 and E = x + 8.
    Now, according to the question,




  • Question 3/10
    1 / -0.25
    Speed of a boat is % faster in downstream than in upstream. It takes 4 hours to cover a distance of 36 km in still water. Speed of stream is how much percent of upstream speed?
    Solutions

    Let the speed of boat in upstream= 6x

    Speed of boat in downstream=  6x= 7x …………..

    Speed of stram= 7x – = 0.5x

    Required percentage= .

  • Question 4/10
    1 / -0.25
    A milkman sells the milk at the cost price. His profit comes after adding water to that milk. If he makes a profit of 25%, what is the ratio of milk and water?
    Solutions
    Let the CP of 1 litre milk be = x 
    The SP of 1 litre milk = x 
    Profit = 25%

    Hence Ratio of milk to water = (x/1.25):(0.25x/1.25) = 1/0.25 = 4:1
    Alternate Solution:
    Let CP of 1 ltr milk be Rs 100 = SP of milk
    Now suppose x ltr of milk is replaced by water to earn profit
    Milk remaining = (1-x)ltr
    New CP = 100(1-x)
    profit = 100 - [100(1-x)] = 100x
    profit% = 25 = [100x / (100 - 100x)]*100
    So x = 0.2ltr
    Milk in this solution = 1-x = 0.8 ltr
    Ratio of milk : water = 4:1
  • Question 5/10
    1 / -0.25
    A can do a certain work in the same time in which B and C together can do it. If A and B together can do it in 10 days and C alone in 50 days, then B alone can do it in how many days?
    Solutions

    (A+B)’s 1 days work =

    C’s 1 days work=

    (A+B+C)’s 1 days work =…………………I

    A’s 1 day’s work =(B+C)’s 1 day’s work…………………. II

    From I and II, we get (A’s 1 day’s work) =

    Therefore, A’s 1 day’s work=

    B’s 1 day’s work

    So, B alone can do the work in 25 days.

    Hence, option A is correct.

    If the total amount spend was Rs 544000 then find the ratio of of savings and expenditure on education together to the expenditure on tour and shopping together.
    Solutions

    Expenditures on savings and education = 25 + 20 = 45%

    Find the central angle made by shopping and tour together.
    Solutions

    Expenditures on shopping and tour = 15 + 10 = 25%

    As we know that 100% = 360 degree

    1% = 3.6 degree

    So, 25% = 253.6=90 degree.
