Let the cost price of article be x :
x + x × ( 15/100 ) = 2300
x + x × ( 5 × 3 / 5 × 20 ) = 2300
x + x × ( 3 / 20 ) = 2300
x + ( 3 × x / 20 ) = 2300
x + ( 3x / 20 ) = 2300
( 20x / 20 ) + ( 3x / 20 ) = 2300
20x + 3x / 20 = 2300
23x / 20 = 2300
Multiply both sides by 20
( 23x / 20 ) × 20 = 2300 × 20
23x = 2300 × 20
23x = 23 × 2000
Divide both sides 23
23x ÷ 23 = ( 23 × 2000 ) ÷ 23
x = Rs 2000
The answer is 179.451 or 1143π/20.
The arc is 254°. A circle is 360°. This means the arc makes up 254/360 of the circle. We will multiply this fraction by the area of the circle, which is
A = πr² = π(9)² = 81π = 254.34
81π(254/360) = 20574π/360 = 1143π/20 = 179.451
The answer is y=-3 hope it helps
