No problem. We can use network marketing as an alternative. The company already has its strong network of customers who can spread the word about its products. They can encourage referral rewards for say every three customers who will buy our product or avail our service.

We can also announce a contest for the customers to buy the product and win a chance to get himself broadcasted for the product advertisement. We can ask them to send in their photo along with the contest application form which they get alongwith the product they buy. So we don’t have to pay them as we would otherwise have to pay to a celebrity.

Depending upon the increase or decrease in price rates, buyers may respond accordingly. Some buyers may assume that quality of the product may have reduced to to reduction in price or that the company may not be selling the product as per expectations. The other assumption that buyers may make is that prices may go down in the future and so may delay purchase. On the other hand increased price may lead to a decrease in demand as the product may be more costly for the consumers who may switch to another seller offering similar products at lower prices.

a.Understanding the customer profile : the tastes,preferences, habits of the customers may differ from person to person.

b.Determining the objective as to who would be the target market, whether the company wants to go for cost minimisation or not etc.

c.Type of channel members :Who all would be involved? Wholesalers, retailers?

d.The criteria on which the channel members would be evaluated and selected.

e.How many intermediaries will be involved in the overall distribution?

The SCPCA method can be used to evaluate channel members.

a) Sales (S): How much sales each channel member can give within a cetain time frame

b) Cost(C): How much cost would be incurred for each channel?

c) Profitability(P): Which channel can give better profitability to the company?

d) Control(C): Whether company can have better control over its channel members or not.

e) Adaptability (A): Whether the channel alternatives are flexible enough to any changes or not. The channel meeting the objectives of the company is selected

Ratio of rates of working of A and B =2:1. So, ratio of times taken =1:2

Therefore, A's 1 day's work=1/9 

B's 1 day's work=1/18 

(A+B)'s 1 day's work= 1/9 + 1/18 = 1/6

so, A and B together can finish the work in 6 days

(A+B)'s 1 day's work=1/20 

C's 1 day work=1/60 

(A+B+C)'s 1 day's work= 1/20 + 1/60 = 1/15

Also A's 1 day's work =(B+C)'s 1 day's work 

Therefore,  we get: 2 x (A's 1 day 's work)=1/15 

=>A's 1 day's work=1/30 

Therefore, B's 1 day's work= 1/20 - 1/30 = 1/60

So, B alone could do the work in 60 days.

P can complete the work in (12 x 8) hrs = 96 hrs 

Q can complete the work in (8 x 10) hrs=80 hrs 

Therefore, P's 1 hour work=1/96   and Q's 1 hour work= 1/80

(P+Q)'s 1 hour's work =(1/96) + (1/80) = 11/480. So both P and Q will finish the work in 480/11 hrs  

Therefore, Number of days of 8 hours each = (480/11) x (1/8) = 60/11

Let the filling capacity of the pump be x m3/min. 

Then, emptying capacity of the pump=(x+10)m3/min.  

so,2400x-2400x+10=8 ⇔x2+10x-3000=0 

⇒x-50+x+60=0 ⇔x=50
