We know that, &#8201; n C r is maximum at middle term. a = &#8201; &#8201; 19 C p = &#8201; 19 C 10 = &#8201; 19 C 9 b = &#8201; &#8201; 20 C q = &#8201; 20 C 10 c = &#8201; &#8201; 21 C 6 = &#8201; 21 C 10 = &#8201; 21 C 11 Hence, a &#8201; 19 C 9 = a 20 10 . &#8201; 19 C 9 = a 21 11 . 20 10 . &#8201; 19 C 9 &#8658; a 1 = b 2 = c 42 11 &#8658; a 11 = b 22 = c 42

If a , b and c are the greatest values of C p 19 , C q 20 and C r 21 respectively, then:
