a man sells a radio set for rupees 605 and gains 10% at what price should he sell another lady of the same kind in order to gain 16%

638 rupees

Step-by-step explanation:

The radio cost him x.

He sold it at a 10% profit for for x + 10% of x which is the same as 1.1x

1.1x = 605

x = 605/1.1 = 550 rupees

It cost him 550 rupees.

To gain a 16% profit, he must sell it for 550 rupees + 16% of 550 rupees

That is the same as 116% of 550 rupees or 1.16 * 550 rupees

1.16 * 550 rupees = 638 rupees

638 rupees

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
