If we arrange the alphabets in the word "RATE" in the English alphabetical order, word "AERT" is formed. Then the third alphabet from the left in this word is "R". similarly, from the word "OPEN" we get - "ENOP" and the third alphabet from the left is "O". From the word "CHEF" we get - "CEFH" the third alphabet from the left "F". From the word "TOY" we get - "OTY" and the third alphabet from the left is "Y". If we use all these letters, then a meaningful English word "FORTY" can be formed.

Ten points are marked on a straight line and eleven points are marked on another straight line. How many triangles can be constructed with vertices from among the above points?
(in 10C2 ways,
i.e., 45 ways) and one point from the line consisting of 11 points (in 11
ways).
So,
the number of triangles here is 45×11=495.
Taking
two points from the line having 11 points (in 11C2,
i.e., 55 ways) and one point from the line consisting of 10 points (in 10
ways), the number of triangles here is 55×10=550
