Shopkeeper purchases the goods of rs 2000 at 20% discount. if he sold at rs 600 less than its marked price. find its profit or loss percentage.

5% loss

Step-by-step explanation:

2000 is the cost price of the shopkeeper. This is after a 20% discount, so the before-discount price would be:

20% reduced of what number is 2000?

We let that price be x, so we can write an equation and solve:

x - 20% of x = 2000

Note: 20% = 20/100 = 0.2

So,

x - 0.2x = 2000

0.8x = 2000

x = 2000/0.8

x = 2500

Now, if he were to sell for 600 less, that would be:

2500 - 600 = 1900

That would be a 2000 - 1900 = 100 LOSS

To find as a percentage, we use the formula:

Where

New = 1900

Old = 2000 (original cost)

Substituting, we find the percentage:

So, that's a 5% loss

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
