If a specific person is always selected, then there will be no total selection left as per the question. If the person is never selected, then he will be removed from all numbers. Total persons = 12-2= 10 People to be selected = 10C4 =10 ! / (10-4)! ×4! =10 ! /6! ×4! =10×9×8×7×6!)/4! ×6! =10×9×8×7)/4×3×2 =10×3×7=210.
If a = 2 + √3, then the value of`(a^(6) + a^(4) + a^(2) + 1)/(a^(3))` is
‘a’ is directly proportional to ‘b’. If at a=30, the value of ‘b’ is 20% greater than ‘a’, then find the value of ‘a’ when b=54.
...If a + b + c = 6, a² + b² + c² = 14 and ab + bc+ ca = 11, then what is the value of a³ + b³ +c³ –3abc?
((99.9 - 20.9)² + (99.9 + 20.9)² )/(99.9 x 99.9 + 20.9 x 20.9) = ?

If 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
If x + y + xy = 118, such that x < y and both 'x' and 'y' are positive integers, then find minimum value of (x + y) .
If a = 32, b = c = 31, then find the value of a 3 + b 3 + c 3 – 3abc.
If a 2 + b 2 = 89 and a 2 - b 2 = 39, then find the value of a 3 - b 3 - 3...
If a = 2 + √3, then the value of (a6 + a4 + a2 + 1)/a3 is
