Question
Let $a$ be a fixed real number such that$\frac{a-x}{p x}=\frac{a-y}{q y}=\frac{a-z}{r z}$If $p, q, \mathrm{r}$ are in A.P. then $x, y, z$ are in(A) A.P.(B) G.P.(C) H. P(D) None of these
Step 1
Step 1: Given that $p, q, r$ are in arithmetic progression, we can write $p - q = q - r = k$ for some real number $k$. Show more…

Let $a, b, c$ be any real numbers. Suppose that there are real numbers $x, y, z$ not all zero such that $x=c y+b z, y$ $=a z+c x$ and $z=b x+a y$. Then $a^{2}+b^{2}+c^{2}+2 a b c$ is equal to (A) 2 (B) $-1$ (C) 0 (D) 1
Let $p, q, r, s$ be real numbers such that $p r=2(q+$ s). Consider quadratic equations $x^{2}+p x+q=0$ and $x^{2}+x+s=0 .$ Then (a) none of these has real roots (b) both have real roots (c) at least one has real roots (d) at most one has real roots
If $p x^{2}+q x+r=0$ has no real roots and $p, q, r$ are real such that $p+r>0$, then (A) $p-q+r \leq 0$ (B) $p+r \geq q$ (C) $p+r=q$ (D) None of these
