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.

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
