Solution : Let the ratio of equal side and unequal side be $5x$ and $7x$.
According to the question,
$5x+5x+7x=34$
⇒ $17x=34$
⇒ $x=2$
The length of equal sides = $5x=5\times2=10$
Hence, the correct answer is 10 cm.

Correct Answer: 5.5

Solution : Average = $\frac{\text{Sum of observations}}{\text{number of observations}}$
Average of first $n$ natural numbers = $\frac{n + 1}{2}$
Here $n$ = 10

Correct Answer: 1

Solution : According to the question
⇒ $\frac{\frac{132}{11}×\frac{13}{12}}{\frac{169}{14}} – \frac{1}{13}$ 
= $\frac{12 × \frac{13}{12}}{\frac{169}{14}} – \frac{1}{13}$
= ${\frac{13}{\frac{169}{14}}} – {\frac{1}{13}}$
= $\frac{14}{13} – \frac{1}{13}$
= $\frac{13}{13}$
= 1
Hence, the correct answer is 1.

Correct Answer: 10%

Solution : The percentage increase in revenue in the year 2010 in comparison to the previous year
= $(\frac{154–140}{140})×100$% [using Percentage Increase = $\frac{\text{final value – initial value}}{\text{initial value}}$×100]
= 10%
Hence, the correct answer is 10%.

Correct Answer: KOZB

Solution : Given:
COAT is written as XLZG.

The opposite letter pairs of the letters of COAT –
C→X; O→L; A→Z; T→G
Thus, COAT is coded as XLZG.
Similarly, follow the same pattern for PLAY –
P→K; L→O; A→Z; Y→B

So, PLAY is coded as KOZB. Hence,
