1.Suppose p,q,r≠0p, q, r \neq 0p,q,r=0 and the system of equations(p+a)x+by+cz=0(p + a)x + by + cz = 0(p+a)x+by+cz=0ax+(q+b)y+cz=0ax + (q + b)y + cz = 0ax+(q+b)y+cz=0ax+by+(r+c)z=0ax + by + (r + c)z = 0ax+by+(r+c)z=0has a non-trivial solution. Then the value of ap+bq+cr\frac{a}{p} + \frac{b}{q} + \frac{c}{r}pa+qb+rc isa.-1b.0c.1d.2Login to continueOnly logged in users canattempt or see the solution.
