If 2z = x + y, then the value of $\frac{x}{x - z}$ + $\frac{y}{y - z}$ is:

A.
0
B.
1
C.
2
D.
5

Answer: Option C

Explanation :

Given, 2z = x + y
⇒ z - x = y - z

Now $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = $\frac{x}{x - z}$ + $\frac{y}{z - x}$

⇒ $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = $\frac{x}{x - z}$ - $\frac{y}{x - z}$

⇒ $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = $\frac{x - y}{x - z}$

⇒ $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = $\frac{x - y}{x - \frac{(x + y)}{2}}$ = 2

∴ $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = 2

Alternately,
Assume x = 2 and y = 4, hence z = 3

Now, $\frac{x}{x - z}$ + $\frac{y}{y - z}$ = $\frac{2}{2 - 3}$ + $\frac{4}{4 - 3}$ = -2 + 4 = 2

Hence, option (c).

6. SSC CHSL 9th June Shift 1 - QA | Coordinate Geometry - SSC

A solid metallic cube of side is $6 \sqrt[3]{4}$ cm, is melted and recast into a cuboid of length 12 cm and breadth 9 cm. What is the length (in cm) of the longest diagonal of the cuboid?

A.
19
B.
18
C.
15
D.
17

Answer: Option D

Explanation :

Side of the cube $6 \sqrt[3]{4}$
Volume of the cube = ${(6 \sqrt[3]{4})}^{3}$ = 864

Volume of the cuboid = 12 × 9 × height = 864

⇒ height = 8

Longest diagonal of the cuboid is the body diagonal

∴ Longest diagonal = $\sqrt{12^{2} + 9^{2} + 8^{2}}$ = 17

Hence, option (d).
