D) A shopkeeper bought two radios for Rs 6,000. He sold one of them at a profit of 20℅ and the other at a loss of 10%. If he gained 2% on his total outlay, at what
he buy each radio?

2400 and 3600

Step-by-step explanation:

Radio 1 cost = x

Radio 2 cost= 6000- x

2

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
