Question : If X, Y, Z, and W are in proportion. X = 3, Y = 13, and W = 39, determine Z.
Option 1: 5
Option 2: 20
Option 3: 15
Option 4: 9
Correct Answer: 9
Solution : Given: X = 3, Y = 13, and W = 39 We know that, if X, Y, Z, and W are in proportion; then $\frac{X}{Y}=\frac{Z}{W}$ Putting the values, we get: ⇒ $\frac{3}{13}=\frac{Z}{39}$ ⇒ $Z=9$ Hence, the correct answer is 9.
Question : The number of students in Class XI in the Science, Arts and Commerce streams of a school over a period of 4 years (2011 2014) has been depicted through the bar chart given below. What is the difference between the averages of the number of Science and Commerce students in the given class over the given period of 4 years?
Option 1: 8
Option 2: 10
Option 3: 12
Option 4: 5
Correct Answer: 5
Solution : From the given bar graph, Total no. of students in science over the given years = 20 + 30 + 40 + 10 = 100 ⇒ Average no. of science students over the given years = $\frac{100}{4}$ = 25 Total no. of students in commerce
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.
The concept of motivation focuses on explaining what 'moves' behaviour. In fact, the term (1)_______ is derived from the Latin word 'movere', referring to movement of activity.

A person will work hard in school, in sports, in business, in music, and in many other situations, if he/she has a very strong need for (4)__________. Hence, motives are the general states that enable us to make predictions about behaviour in many different situations. In other words, motivation is one of the (5)_________ of behaviour. Instincts, drives, needs, goals, and incentives come under the broad cluster of motivation. Question: Select the most appropriate option to fill in the blank number (1).

Question : If the radius of a sphere is doubled, then its surface area will be increased by:
Option 1: 100%
Option 2: 200%
Option 3: 300%
Option 4: 400%
Correct Answer: 300%
Solution : Given that the radius of a sphere is doubled. Let initial radius = $r_0$ We know that the surface area of a sphere = $4\pi r^2$ ⇒ Initial surface area = $4\pi r_0^2$ Now, final radius = $2r_0$ ⇒ Final surface area =$4\pi(2r_0)^2$ = $4×4\pi

Question : If the value of $\operatorname{cosec} A + \cot A = m$, then the value of $\operatorname{cosec} A - \cot A$ is:
Option 1: $\frac{1}m$
Option 2: $m$
Option 3: $\sqrt{m}$
Option 4: $m^2$
Correct Answer: $\frac{1}m$
Solution : Given: $\operatorname{cosec} A + \cot A = m$ We Know that, $\operatorname{cosec}^2 A - \cot^2 A = 1$ $⇒(\operatorname{cosec} A - \cot A)(\operatorname{cosec}A + \cot A) = 1$ Substituting $m$ for $\operatorname{cosec} A + \cot A$, we get: $\therefore\operatorname{cosec} A - \cot A = \frac{1}{m}$
