A shopkeper declares a 20% discount on his goods and sells it at a profit of 25%. What is the cost price of the goods if the mar

A 20% discount means you pay 80% of the marked price.

Why 80%? Well, 100% - 20% = 80%.

The discounted price is 80% times $2000.

Let D = discounted price

D = 0.80($2000) = $1600 

What is profit?

Profit = (discounted price - cost)/cost

Let c = cost

We are looking for c.   

($1600 - c)/c = 0.25

Multiply both sides by c. 

$1600 - c = 0.25c 

$1600 = 1.25·cosc 

c = $1600/1.25 = $1280

Answer: $1280

A is 5 years older than T. In 3 years, T will be 2/3 A age. How old is A?
Ivanshal [37]

Answer:

12 years

Step-by-step explanation:

T + 5 = A

Therefore T =A - 5

In three years T = 3+ (A-5)

thus T = A - 2

Also in three years T = 2/3 (A+3)

Equating the two

A -2 = 2/3 (A+3)

3A - 6 = 2A + 6

3A - 2A = 6 + 6

Therefore A = 12

Absolute values just make the number positive if it is negative. The number stays positive if it’s positive.
