Time and Work Problems shortcut trick type #5

2 men or 5 women

or 10 children can do a piece of work in 36
days. In how many days, 1 man and 1 woman or 2 children can do that work?

Here is the shortcut trick for this type of question.

Let m denotes man

And w denotes woman

And c denotes children

The equation in the given question is

2m=5w=10c=36

Now equating men and women to children respectively,

2m=10c

so 1m=5c

and also 5w=10c

so 1w= 2c

putting these values in question to be answered

1m+1w+2c=?

5c+2c+2c=36
(putting the values of m and w shown above)

9c=36

So c=4

Now multiply this value of c to the given no. of children
i.e.

10*4=40 days Ans.

So 1 man and 1 woman and 2 children will do that work in 40
days. Ans.

For better understanding, let us take another example.

3 men or 4 women or 12 children can do a work in 44 days. Determine
in how many days, 2 men and 3 women and 5 children can do that work?

Let us do this question now with shortcut method

3m=4w=12c=44

3m=12c

1m=4c

So 2m=8c (2m are
asked in question)

Also 4w=12c

1w=3c

So 3w=9c

putting these values in question to be answered

2m+3w+5c=?

8c+9c+5c=44

22c=44

So c=2

Now multiply this value of c to the given no. of children
i.e.

12*2=24 days Ans.

Now practice all time and work problems of this type. You
can solve this type of questions in just 10 seconds if you practice this

trick
as you don’t have to write all the steps in the exam. You just have to find the
answer.

So in your practice of these time and work question, just
equate all the ‘or’ men and women and boys and find their equality and put them
equal to days as shown above.

Hope you like the trick if you are able to understand the
trick.
