  9. Arun Says:

    the answer are
    1- 1
    2- 3
    3 – 1

    solution
    1
    since they both can do work in 1 day is 60/11
    so two days is 120/11(first statement – they work alternate days)
    now since 120/11 will be 10 days + one incomplete day the work is completed.
    question asked on which it will be completed the answer is 11th day

    solution 2
    the solution only by using the both the statements described
    hence
    solution is a is greater

    solution 3

    let the salary and expenditure is x& y respectively

    the income is x and 3x/5 and expenditure is y and 4y/9
    hence x-y = 700 and 3x/5 – 4y/9 = 700(first statement alone)
    x=2500 y= 1500

    @ ARUN
    Dear they are not working together…
    If work left on 11th day is less than 1/12 only then work will be completed on 11th day.. if work left if greater than 1/12 and less than 1/10 it will depend on whose started the work.


  11. dhivya Says:

    answer for (1) is 3…cuz work done for first three days if A starts the work is 17/60 , if B starts the work first for 3 days thy wud have completed 16/60 .so its necessary use the second statement also.

    ques(2)3rd choice
    ques (3) is 2nd choice
