Q53.If a, b and c are the greatest values of 19Cp, 20Cq and 21Cr respectively, then: (1) 11 a = 22b = 21c (2) 10a = 11b = 21c (3) 11 a = 22b = 42c (4) 10a = 11b = 42c
What This Question Tests
This question tests the understanding of how to find the greatest value of binomial coefficients (nCr) for different 'n' and then establish a relationship between these maximum values.
Concepts Tested
Formulas Used
nCr = n! / (r! * (n-r)!)
nCr is maximum when r = n/2 or (nยฑ1)/2
