Answer 1

750= 5x+ 8x × 50/100 +4x ×25/100

750=5x+ 8x/2+x

750= 5x+5x

750=10x

x=750/10=75

So, no.of coins of 1 rupee=5x=75×5=375

no.of coins of 50 p=8 ×75=600

no.of coins of 25p=4×75= 300

Answer 2

Explanation:

What are Polygons?

A Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane. Polygon is the combination of two words, i.e. poly (means many) and gon (means sides).

A minimum of three line segments is required to connect end to end, to make a closed figure. Thus a polygon with a minimum of three sides is known as Triangle and it is also called 3-gon. An n-sided polygon is called n-gon.
