Option 2: 2
Option 3: 4
Option 4: 3

Question : Two successive discounts, each of $x\%$ on the marked price of an article, are equal to a single discount of INR 331.20. If the marked price of the article is INR 920, then the value of $x$ is:
Option 1: 20%
Option 2: 15%
Option 3: 25%
Option 4: 18%
Correct Answer: 20%
Solution : 1st discount = $x\% \times 920 = 9.2x$ Amount after discount = $920 - 9.2x$ 2nd discount $x\% \times(920 - 9.2x)=\frac{(920 - 9.2x)x}{100}$ According to the question, $9.2x + \frac{(920 - 9.2x)x}{100} = 331.20$ ⇒ $920x + 920x - 9.2x^2 = 33120$ ⇒ $9.2x^2 -
Question : An electron microscope gives higher magnifications than an optical microscope because:
Option 1: The velocity of electrons is smaller than that of light.
Option 2: The wavelength of electrons is smaller as compared to the wavelength of visible light.
Option 3: The electrons have more energy than the light particulars.
Option 4: The electron microscope uses more powerful lenses.
Correct Answer: The wavelength of electrons is smaller as compared to the wavelength of visible light.
Solution : The correct option is The wavelength of electrons is smaller as compared to the wavelength of visible light.
Electron microscopes have greater magnifications than optical microscopes because electron wavelengths are much
Question : The difference between CI and SI for 2 years at a 10% rate of interest is Rs. 4. Find the sum of money:
Option 1: Rs. 400
Option 2: Rs. 200
Option 3: Rs. 300
Option 4: Rs. 800
Correct Answer: Rs. 400
Solution : Given: The difference between CI and SI for 2 years at a 10% Rate of interest is Rs. 4. Difference between Compound Interest and Simple Interest for 2 terms = $\frac{PR^{2}}{100^{2}}$, where $R$ is the rate of interest per term and $P$ is principal.
Question : Directions: The expenses of a country for a particular year are given in the pie chart, Read it carefully and answer the question: The percentage of the total amount spent on health is:
Option 1: 15%
Option 2: 20%
Option 4: 30%
Correct Answer: 15%
Solution : We know that 360° = 100% Health is represented by 54°. So, 54° = $\frac{100 \times 54}{360}$ = 15% Hence, the correct answer is 15%.
Question : The twin paradox is associated with:
Option 1: The theory of relativity
Option 2: Particle physics
Option 3: Hydrodynamics
Option 4: Quantum mechanics
Correct Answer: The theory of relativity
Solution : The correct answer is the theory of relativity.
A thought experiment known as the twin paradox helps explain special relativity's theory of time dilation. In the twin paradox, one twin remains on Earth while the other goes close to the speed
Question : Directions: If × means +, ÷ means ×, − means ÷, and + means −, then what will be the value of the following expression? 32 × 6 + 10 − 4 ÷ 8 = ?
Option 1: 18
Option 2: 20
Option 3: 22
Option 4: 24
Correct Answer: 18
Solution : Given: 32 × 6 + 10 – 4 ÷ 8 = ?
On interchanging the mathematical signs, we get – = 32 + 6 – 10 ÷ 4 × 8 = 32 + 6 – 2.5 × 8 = 32 + 6 – 20 =
