1) 810+18*3^1/2



2) 810-18*3^1/2



3) 810-249*3^1/2



4) 810+24*3^1/2 Skip



Should be 810 + 81*3^1/2

In three distinct regular polygons, it is known that the measure of the internal angle of one regular polygon exceeds the measure of the internal angle of the other two regular polygons by 15° and 27° respectively. Furthermore, the sum of the measures of the external angles of all the three regular polygons is 177°. What is the sum of the number of sides of all these three regular polygons

How does the questions from number system arise in main cat examination? I don't think questions based on the theorems such as wilsons and others will be given.

Question Types:

if a+b+c+d=12 and a,b,c,d restricted to

case1:3

case2:4

case3:5

case4:6

case5:7....upto 9

Its hard to approach these problems when given a large value Eg:a+b+c+d=180

So please help me with an article/ link/comments😠
