An item was sold at loss of 20%. had it been sold for rs3000 more then the profit would have been 10%. what is the cost price of the item

10000

Step-by-step explanation:

Assumed that the cost price of the item is x.

It was sold at a loss of 20%:

therefore the price sold was 0.8x

If it was sold at a profit of 10%:

the price sold would have been 1.1x

Since the difference in price is 3000:

1.1x - 0.8x = 3000

0.3x = 3000

x = 10000

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
