a man makes a profit 15% by selling an article for rs.250. for what amount should he sell it to make profit of 38%​

$300

Step-by-step explanation:

original price = $250

the profit= 15%

ok now let the cost price of article be ₹ x

x + 15% of x = 250

1.15x = 250 => 115x ÷ 100 = 250

115x = 25000 => x = 25000 ÷ 115

x = 5000/ 23

cost price of article = ₹5000/ 23

required profit = 38%

= 38% of 5000/ 23 = 0.38 × 5000/ 23

= 1900/ 23

the required will be selling price to gain about 38%

= cost price + required profit which is

= (5000/ 23) + (1900/ 23)))

= 6900/ 23 = $300

 now its required selling price = $300

1/5^2 = 7.56/45

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
