Vitamin D is also known as calciferol. Vitamin D aids bone health, immunological function, and cell development. Carotene is a carotenoid, which is a kind of plant pigment with antioxidant characteristics. In the body, carotenoids can
Question : In a particular system, the units of length, mass, and time are chosen to be 10 cm, 10 g and 0.1 s respectively. The unit of force in this system will be equivalent to:
Option 1: 0.1 N
Option 2: 1 N
Option 3: 10 N
Option 4: 100 N
Correct Answer: 0.1 N
Solution : The correct option is 0.1 N.
The units of length, mass and time in the provided system are 10 cm, 10 g, and 0.1 s, respectively. The formula a = v/t, where v is the change in velocity and t is the change
Question : In India, palm, coconut, keora, and agar are the common trees of which of the following forests?
Option 1: Mangrove Forests
Option 2: Tropical Evergreen Forests
Option 3: Tropical Deciduous Forests
Option 4: Montane Forests
Correct Answer: Mangrove Forests
Solution : The correct answer is Mangrove Forests.
Mangrove forests are found along tide-influenced coastal locations. These coastlines accumulate silt and mud. The most prevalent type of mangroves are dense ones, in which the plant roots are underwater.
Such vegetation covers the deltas of the Godavari,
Question : Directions: What will come in place of the question mark (?) in the following equation if + and × are interchanged and – and ÷ are interchanged? 2 + 6 ÷ 8 – 4 × 14 = ?
Option 1: 19
Option 2: 15
Option 3: 12
Option 4: 24
Correct Answer: 24
Solution : Given: 2 + 6 ÷ 8 – 4 × 14 = ?
After interchanging + with ×, and – with ÷, the equation will be as follows – = 2 × 6 – 8 ÷ 4 + 14 = 2 × 6 – 2 +

Question : If $\cot B=\frac{15}{8}$, where $B$ is an acute angle, what is the value of $\sec B+\tan B$?
Option 1: $\frac{4}{5}$
Option 2: $\frac{5}{3}$
Option 3: $\frac{5}{4}$
Option 4: $\frac{3}{5}$
Correct Answer: $\frac{5}{3}$
Solution : Given: $\cot B=\frac{15}{8}$ We know that $\cot B=\frac{\text{base (b)}}{\text{perpendicular (p)}}=\frac{15}{8}$ So, $h^2 = \sqrt{b^2+p^2}$ where $h$ is hypotenuse. ⇒ $h^2 = \sqrt{15^2+8^2}$ ⇒ $h^2 = \sqrt{225+64}$ ⇒ $h^2 = \sqrt{289}$ ⇒ $h = 17$ Thus, $\sec B+\tan B$ $= \frac{\text{h}}{\text{b}}+\frac{\text{p}}{\text{b}}$ Putting the values of $p,
Question : The line chart given below shows the number of pencils sold by two shopkeepers A and B in 5 months.
Which of the following statements is correct? I. The number of pencils sold by A in P and Q together is 31.72 percent more than the number of pencils sold by B in S and T together. II. The number of pencils sold by B in Q and R together is 105.88 percent of the number of pencils sold by A in P and T together.
Option 1: Neither I nor II
Option 2: Only I
Option 3: Only II
Option 4: Both I and II
Correct Answer: Only II
Solution : Statement I: Number of pencils sold by A in P and Q together = 150 + 140 = 290 Number of pencils sold by B in S and T together = 130 + 125 = 255 Percent of number of pencils sold by A
Question : The degree of dissociation of an electrolyte depends on
Option 1: dilution
Option 2: impurities
Option 3: atmospheric pressure
Option 4: method of dissolution
Correct Answer: dilution
Solution : The correct answer is dilution.
Dilution is one of the variables that influences an electrolyte's degree of dissociation. An electrolyte loses concentration as it becomes diluted. It suggests that the ions have more space to travel and dissociate from one another. The degree of separation
