If a + b + c = 6, a² + b² + c² = 14 and a³ + b³ + c³ = 36, then the value of abc is

If (10 a³+4b³):(11a³-15b³)=7:5, then (3a+5b):(9a-2b)=?

If x = y = 333 and z = 334, then the value of x³ + y³ + z³ – 3xyz is

If p, q, r are all real numbers, then (p – q)³ + (q – r)³ + (r – p)³ is equal to 

and x is real, then the value of is

If x = 332, y = 333, z = 335, then the value of x³ + y³ + z³ – 3xyz is

Directions: In each of these questions, two equations (i) and (ii) are given, you have to solve both the equations and give answer accordingly.

(i) 6x² – 11x + 4 = 0
 (ii) 3y² – 5y + 2 = 0

If a + b + c = 6, a³ + b³+c³-3abc=342, then what is the value of ab + bc + ca?
