Question : Directions: Select the triad in which the numbers are related in the same way as the numbers of the following triads. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 3 – 4 – 24 4 – 7 – 56
Option 1: 9 –12 – 54
Option 2: 8 – 7 – 53
Option 3: 2 – 3 – 18

Question : What is the value of $\frac{3}{5}(\sec^2 20^\circ - \cot^2 70^\circ)$?
Option 1: $\frac{4}{3}$
Option 2: $\frac{5}{3}$
Option 3: $\frac{2}{5}$
Option 4: $\frac{3}{5}$
Correct Answer: $\frac{3}{5}$
Solution : $\frac{3}{5}(\sec^2 20^\circ - \cot^2 70^\circ)$ $=\frac{3}{5}(\sec^2 20^\circ - \tan^2 20^\circ)$ [By using: $\tan\theta = \cot(90^\circ-\theta)$] $=\frac{3}{5}\times1$ [We know that $\sec^2 \theta- \tan^2 \theta = 1$] $=\frac{3}{5}$ Hence, the correct answer is $\frac{3}{5}$.
Question : Where do plants synthesise protein from?
Option 1: Fatty acids
Option 2: Sugar
Option 3: Amino acids
Option 4: Starch
Correct Answer: Amino acids
Solution : The correct option is Amino acids.
