Answer:
Step-by-step explanation:
number of work by men=1/x
number of work by boy=1/y
and by given the condition(1)
2/x+7/y=1/4
2a+7b=1/4
8a+28b=1
condition(2)
4/x+4/y=1/3
4a+4b=1/3
12a+12b=1
now solve (1) and (2)
(1) x 3 = 24a + 84b =3
(2) x 2=24a + 24b = 2
(subtract it)
-----------------------------------
60b=1
b = 1/60
therefore y = 60
now substitute b=1/60 in equation (2)
12a + 12 x 1/60 =1
12a + 1/5 =1
60a + 1/5=1
60a+1=5
60a = 4
a=1/15
therefore x=15
