Answer 1

Answer: 18 , 36

Step-by-step explanation: 1 boy = x days

                                              1 day = 1/x

                                               1 man = y days

                                               1 day = 1 / y  

GIVEN

4/x + 4/y = 1 /3

2/x + 5/y  = 1/4

p = 1/x , q = 1/y

4p + 4q = 1/3

2p + 5q = 1/4

 [4p + 4q = 1/3] 1  ........... eq. 1

  [ 2p+ 5q = 1/4 ] 2 ..............eq. 2

eq1 - eq2

4p + 4q = 1/3

 4p + 10q = 1/2

-----------------------

     -6q = - 1/6

        q = 1 / 36

         x = 36 [ men ]

     y = 18 [boys ]
