3. Let the total job be equal to 'T' units.
Let the job completed by models A, B and C in one minute be equal to a, b and c units repectively.
From the given information, we get the following equations
25a+25b+25c = T...................Eqn1
20a+50b = T...................Eqn2
30b+60c = T...................Eqn3
By solving the above equations we get the ratio a : b : c = 5 : 4 : 3
Therefore, model A is the fastest.
As a : b : c = 5 : 4 : 3, let a, b, c be 5, 4, 3 respectively.
T = 25 (5+4+3) =300.
Therefore, A takes 300/5 minutes i.e., 60 minutes to complete the entire job.
4. Let a, b and c be the number of TV ads, Radio ads and Internet ads respectively.
From the given information, we get the following equations
a+b+c = 144.................Eqn1
1500a+600b+400c= 72000.
As a, b, c are non-negative integers, by solving the above equations we get different sets of values for a,b,c as follows:
(a, b, c) = (0, 72, 72) or (2, 61, 81) or (4, 50, 90) or (6, 39, 99) or (8, 28, 108) or (10, 17, 117) or (12, 6, 126).
Therefore, in the above seven different ways the ads can be distributed amon TV, Radio and Internet.
