With A,B combinations C or D or E are possible, with A,C combinations B or D or E are possible, with A,D combinations B or C or E are possible, with A,E combinations B or C or D are possible
So total 12 combinations for A are possible for selecting 3 among 5 like (A,B,C), (A,B,D), (A,B,E), (A,C,B), (A,C,D), (A,C,E), (A,D,B), (A,D,C), (A,D,E), (A,E,B), (A,E,C), (A,E,D)
Similar 12 combinations are possible for remaining 4

ABC is a right-angle triangle with sides R1, R2 and R3 such that no sides are even simultaneously. If 102 is added to all sides and then squared we get S1, S2, S3 (Sn=square of (Rn+102)). If T= S1+S2+S3.
Then, which is always true for T.

2. divisible by 4 not by 8
3. divisible by 8 not by 4
4. none of the above

as given condn 2 of R1, R2 and R3 will be odd nos
consider tr (3,4,5)
then T = (3+102)^2 + (4+102)^2 + (5+102)^2
= (3^2+4^2+5^2)+ 3*102^2 + 2*102*(3+4+5)

In a triangle ABC, points P1, Q1, R1 divide the lines AB, BC and AC respectively in the ratio 3 : 2 each. In the triangle P1 Q1 R1, the points P2, Q2 and R2 divide the sides P1Q1, Q1R1 and P1R1 in the ratio 3 : 2 each. A new triangle is constructed by joining the points on the sides of triangle P2Q2R2 that divide these sides in the ratio 3 : 2. This process of forming triangles continues infinitely. Find the ratio of the area of triangle P1Q1R1 to the sum of the areas of all the formed/constructed triangles (P2Q2R2, P3Q3R3…) whose areas are smaller than the area of the triangle P1Q1R1.
