Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): No notebook is a diary – According to the Venn diagram, all diaries are books and no book is a notebook. So,
Question : $\frac{2\sin68°}{\cos22°}-\frac{2\cot15°}{5\tan75°} -\frac{3\tan45°\cdot\ \tan20°\cdot\ \tan40°\cdot\ \tan50°\cdot\ \tan70°}{5}$ is equal to:
Option 1: –1
Option 2: 0
Option 3: 1
Option 4: 2
Correct Answer: 1
Solution : $\frac{2\sin68°}{\cos22°}-\frac{2\cot15°}{5\tan75°} - \: \frac{3\tan45°.\tan20°.\tan40°.\tan50°.\tan70°}{5}$ = $\frac{2\sin68°}{\cos(90°-68°)}-\frac{2\cot(90°-75°)}{5\tan75°} - \frac{3\cdot 1\cdot\tan20°\cdot\tan40°\cdot\tan(90°-40°)\cdot\tan(90°-20°)}{5}$ = $\frac{2\sin68°}{\sin68°}-\frac{2\tan75°}{5\tan75°} -\frac{3\cdot 1\cdot\tan20°\cdot\tan40°\cdot\cot40°\cdot\cot20°}{5}$ = $2×1 - \frac{2}{5}× 1 - \frac{3}{5}$ = $2-\frac{2}{5}-\frac{3}{5}$ = $\frac{10-2-3}{5}$ = $1$ Hence, the correct answer is 1.

Question : Directions: In the following question, one statement is given followed by two assumptions I and II. You have to consider the statement to be true, even if it seems to be at variance from commonly known facts. You have to decide which of the given assumptions, if any, follows from the given statement. Statement: The impact of economic sanctions on the economy, which is already so weak could be devastating. Assumptions: I. Economic sanctions impact only a weak economy. II. The impact of economic sanctions varies from economy to economy.
Option 1: Only II is implicit
Option 2: Neither I nor II is implicit
Option 3: Both I and II are implicit
Option 4: Only I is implicit
Correct Answer: Only II is implicit
Solution : Let's analyse the given assumptions – Assumption I: Economic sanctions impact only a weak economy – The given statement does not specify which economy the economic sanctions will impact. However, it is stated that if the economy is already weak, the impact
Question : The length, breadth, and height of a room are 7 m, 5 m, and 3 m, respectively. Find the cost of whitewashing the walls of the room and the ceiling at the rate of INR 16 per m2.
Option 1: INR 1,712
Option 2: INR 1,742
Option 3: INR 1,698
Option 4: INR 1,684
Correct Answer: INR 1,712
Solution : Length = 7 m, Breadth = 5 m, Height = 3 m Area of four walls = $\text{2(length +breadth) × height}$ = 2(7 + 5) × 3 = 2 × 12 × 3 = 72 m$^2$ Area of ceiling = $\text{length × breadth}$ =
