Correct Answer: 10

Solution : Given: $\frac{3–5x}{2x}+\frac{3–5y}{2y}+\frac{3–5z}{2z}=0$
⇒ $\frac{3}{2x}–\frac{5x}{2x}+\frac{3}{2y}–\frac{5y}{2y}+\frac{3}{2z}–\frac{5z}{2z}=0$
⇒ $\frac{3}{2x}+\frac{3}{2y}+\frac{3}{2z}–\frac{5x}{2x}–\frac{5y}{2y}–\frac{5z}{2z}=0$
⇒ $\frac{3}{2}(\frac{1}{x}+\frac{1}{y}+\frac{1}{z})–\frac{5}{2}–\frac{5}{2}–\frac{5}{2}=0$
⇒ $\frac{3}{2}(\frac{1}{x}+\frac{1}{y}+\frac{1}{z})=\frac{5}{2}+\frac{5}{2}+\frac{5}{2}$
⇒ $(\frac{1}{x}+\frac{1}{y}+\frac{1}{z})=\frac{15}{2}×\frac{2}{3}$
⇒ $2(\frac{1}{x}+\frac{1}{y}+\frac{1}{z})=\frac{15}{2}×\frac{2}{3}×2$
⇒ $\frac{2}{x}+\frac{2}{y}+\frac{2}{z}=10$
Hence, the correct answer is 10.

Correct Answer: 74

Solution : Given:

102, 101, 98, 93, 86, 74, 66, 53

Let's find the difference between the numbers  →

102 – 101 = 1

101 – 98 = 3

98 – 93 = 5

93 – 86 = 7

86 – 74 = 12

74 – 66

Correct Answer: –1

Solution : Given: $9x^2+16y^2=60$ and $3x+4y=6$
$3x+4y=6$
Squaring both sides of the above expression, we get,
⇒ $(3x+4y)^2=6^2$
⇒ $9x^2+16y^2+24xy=36$
Substitute the value of $9x^2+16y^2=60$ in the above expression, we get,
$60+24xy=36$
⇒ $24xy=36-60$
⇒ $24xy=–24$
⇒ $xy=–1$
Hence, the correct answer is –1.
