The price of a product is $a. Bill bought s products and then sold 80 percents of them $b. which of the following represents the whole deal if Bill's profit was three times the cost?
A. 0.8sb = 4sa.
B. (1-0.8) s ab = 3s.
C. 3(0.8a sb) = sa.
D. (s-0.8s) (b-a) = 3.
E. (s0.8s) / (b-a) = 3.
A. 0.8sb = 4sa.
B. (1-0.8) s ab = 3s.
C. 3(0.8a sb) = sa.
D. (s-0.8s) (b-a) = 3.
E. (s0.8s) / (b-a) = 3.

The total price at which Bill bought the products is \(s*$a\)
Bill, then sold 80% of the products at $b. The price realized from the sale is \(0.8s*$b\)
The total profit which is generated by this transaction is \(3*s*$a\)(at three times the cost)
Therefore, the whole deal is Profit = SP - CP -> \(3sa = 0.8sb - sa\) -> 4sa = 0.8sb(Option A)

Solution
Given:
- • The cost price of a product = $a
• Bill bought ‘s’ products and then sold 80% of them at $b each
• Bill’s profit = 3 * CP
To find:
- • Which among the given answer choices represents the whole deal
Approach and Working:
- • Total CP = $a * s
• Total SP = \($b * \frac{80s}{100}\)
• Profit = \(3as = \frac{4bs}{5} – as\)
o Implies, 4as = 0.8sb
Hence, the correct answer is Option A
Answer: A
