Question : Simplify. $\frac{\sin8\theta \cos\theta - \sin6\theta \cos3\theta}{\cos2\theta \cos\theta - \sin3\theta \sin4\theta}$
Option 1: $\cot \theta$
Option 2: $\cot 2 \theta$
Option 3: $\tan \theta$
Option 4: $\tan 2 \theta$
Correct Answer: $\tan 2 \theta$
Solution : Given: $\frac{\sin8\theta \cos\theta - \sin6\theta \cos3\theta}{\cos2\theta \cos\theta - \sin3\theta \sin4\theta}$ = $\frac{2\sin8\theta \cos\theta - 2\sin6\theta \cos3\theta}{2\cos2\theta \cos\theta - 2\sin3\theta \sin4\theta}$ = $\frac{\sin(8\theta+\theta)+\sin(8\theta-\theta)-\sin(6\theta+3\theta)-\sin(6\theta-3\theta)}{\cos(2\theta+\theta)+\cos(2\theta-\theta)-\cos(3\theta-4\theta)+\cos(3\theta+4\theta)}$ = $\frac{\sin9\theta + \sin7\theta - \sin9\theta - \sin3\theta}{\cos3\theta + \cos\theta - \cos(-\theta)+cos7\theta}$ = $\frac{\sin7\theta-\sin3\theta}{\cos3\theta + \cos\theta - \cos\theta+cos7\theta}$ = $\frac{\sin7\theta-\sin3\theta}{\cos7\theta+cos3\theta}$ =
Question : When Lead nitrate is heated, which of the following gases is produced?
Option 1: Nitrogen oxide
Option 2: Lead dioxide
Option 3: Nitrogen dioxide
Option 4: Lead oxide
Correct Answer: Nitrogen dioxide
Solution : The correct option is Nitrogen dioxide.
When Lead Nitrate (Pb(NO3)2) is heated, it undergoes thermal decomposition. The reaction can be represented as: Pb(NO3)2(s) → PbO(s) + NO2(g) + O2(g)
When Lead
Question : After 55 years, a sum invested at simple interest at the rate of $r$ percent becomes twice of itself. What is the value of $r$?
Option 1: $\frac{17}{20}\%$
Option 2: $\frac{11}{30}\%$
Option 3: $\frac{13}{15}\%$
Option 4: $\frac{20}{11}\%$
Correct Answer: $\frac{20}{11}\%$
Solution : Time = 55 years Principal = $\text{P}$ Rate = $\text{r}$ Amount = $\text{2P}$ Simple interest = Amount – Principal = $\text{2P – P = P}$ We know that, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ $⇒\text{P} = \frac{\text{P × r × 55}}{100}$ $⇒\text{r} =
Question : Directions: Given below are two statements and two conclusions. Take the statements to be true even if they are at variance with commonly known facts, and decide whether the conclusion(s) follow(s) the given statements. Statements: Some cakes are biscuits. Some biscuits are chocolates. Conclusions: I. Some biscuits are cakes. II. Some cakes are chocolates.
Option 1: Both the conclusions follow
Option 2: Only conclusion II follows
Option 3: Neither conclusion I nor II follows
Option 4: Only conclusion I follows

Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyze the conclusions – Conclusion I: Some biscuits are cakes – From the Venn diagram, it is evident that the circles representing biscuits and cakes overlap and have
Question : _____ is a hormone that regulates the amount of glucose in the blood.
Option 1: Glycogen
Option 2: Thyroxine
Option 3: Oxytocin
Option 4: Insulin
Correct Answer: Insulin
Solution : The correct answer is Insulin.

Question : The antiseptic compounds present in dettol is
Option 1: Iodine
Option 2: Chloroxylenol
Option 3: Biothional
Option 4: Cresol
Correct Answer: Chloroxylenol
Solution : The correct option is Chloroxylenol
Dettol, an antiseptic and disinfectant often used to treat wounds and surfaces to prevent infection, contains the active component chloroxylenol. Chloroxylenol has antibacterial characteristics and is efficient against a variety of bacteria as well as some fungi. It acts by
Question : The cost price of an article is INR 2,800. Profit as a percentage of the selling price is 20%. What is the actual profit (in INR)?
Option 1: INR 616
Option 2: INR 504
Option 3: INR 700
Option 4: INR 560
Correct Answer: INR 700
Solution : Given: The cost price (CP) of an article is INR 2,800 and the profit is 20% Profit = (Selling price – Cost price) Profit percentage = $\frac{\text{Profit}}{SP} \times 100$ According to the question, $20 = \frac{\text{Profit}}{SP} \times 100$ ⇒ $20 = \frac{SP–2800}{SP} \times 100$
Question : The bar graph given below shows the percentage distribution of the total production of six different types of cars by a car manufacturing company over 2 years. Percentage of six different types of cars manufactured by a Company over Two Years
The total number of cars of type P, R, and U manufactured in 2001 is:
Option 1: 1,54,000
Option 2: 1,76,000
Option 3: 2,00,000
Option 4: 2,64,000
Correct Answer: 2,64,000
Solution : Total number of cars manufactured in 2001 = 4,40,000 Percentage of cars type P manufactured = 40% Percentage of cars type R manufactured = (75 – 60)% = 15% Percentage of cars type U manufactured = (100 – 95)% = 5% So, total required cars
