Option 4: $\frac{24}{25}$
Correct Answer: $\frac{24}{25}$
Solution : Given, $\sin \theta=\frac{6}{10}$ and $\cos\theta = \frac{8}{10}$ $\sin2\theta =2\sin\theta\cos\theta$ ⇒ $\sin2\theta = 2\times \frac{6}{10}\times\frac{8}{10}$ ⇒ $\sin\theta = 2\times \frac{3}{5}\times \frac{4}{5}$ ⇒ $\sin2\theta = \frac{24}{25}$ Hence, the correct answer is $\frac{24}{25}$.

Option 1: 2.66
Option 2: 1.16
Option 3: 0.55
Option 4: 4.66
Correct Answer: 1.16
Solution : L1 = (Total male teachers) – (Total female teachers) = $(240+320+280+200+120)-(320+280+80+40+40+120)$ = $1160 - 880=280$ L2 = Total number of male and female teachers in school H = $120 + 120= 240$ Ratio = $\frac{\text{L1}}{\text{L2}}=\frac{280}{240}=\frac{7}{6} = 1.16$ Hence, the correct answer is 1.16.
