Question : Which of the following is TRUE? I. $\frac{1}{\sqrt[3]{12}}>\frac{1}{\sqrt[4]{29}}>\frac{1}{\sqrt5}$ II. $\frac{1}{\sqrt[4]{29}}>\frac{1}{\sqrt[3]{12}}>\frac{1}{\sqrt5}$ III. $\frac{1}{\sqrt5}>\frac{1}{\sqrt[3]{12}}>\frac{1}{\sqrt[4]{29}}$ IV. $\frac{1}{\sqrt5}>\frac{1}{\sqrt[4]{29}}>\frac{1}{\sqrt[3]{12}}$
Option 1: Only I
Option 2: Only II
Option 3: Only III
Option 4: Only IV
Correct Answer: Only III
Solution : Calculating the values: (taking the 12th power of each term) $\frac{1}{\sqrt[3]{12}} \rightarrow \frac{1}{12^4} = \frac{1}{20736}$ $\frac{1}{\sqrt[4]{29}} \rightarrow \frac{1}{29^3} =\frac{1}{24389}$ $\frac{1}{\sqrt5} \rightarrow \frac{1}{5^6} = \frac{1}{15625}$ In fractions, the fraction value is low for fractions with large denominators. Comparing these values, we get: $\frac{1}{\sqrt5} >\frac{1}{\sqrt[3]{12}}
Question : Which enzyme digests proteins in the stomach?
Option 1: Trypsin
Option 2: Pepsin
Option 3: Salivary amylase
Option 4: Pancreatic enzyme
Correct Answer: Pepsin
Solution : The correct option is Pepsin.
Pepsin is the enzyme that digests proteins in the stomach. The chief cells in the stomach lining generate pepsin in an inactive state known as pepsinogen. Pepsinogen is activated and transformed into pepsin when it comes into contact with the
Question : While baking a cake for 15 people, Jaya used 2.4 kg of flour. How much flour will she need to bake a similar cake for 36 people?
Option 1: 5.60 kg
Option 2: 6.00 kg
Option 3: 5.88 kg
Option 4: 5.76 kg
Correct Answer: 5.76 kg
Solution : For 15 people Jaya uses 2.4 kg of flour. For 1 person Jaya uses $\frac{2.4}{15}$ kg of flour. $\therefore$ For 36 people Jaya uses $\frac{2.4\times36}{15}$ = 5.76 kg of flour Hence, the correct answer is 5.76 kg.

Question : For what value of m will the system of equations $17x + my + 102 = 0$ and $23x + 299y + 138 = 0$ will have an infinite number of solutions?
Option 1: 221
Option 2: 223
Option 3: 220
Option 4: 219
Correct Answer: 221
Solution : Given: $17x + my + 102 = 0$ and $23x + 299y + 138 = 0$ $a_1x + b_1y + c_1 = 0$ $a_2x + b_2y + c_2 = 0$ The condition for an infinite number of solutions is $\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}$ According to the question, $\frac{17}{23}=\frac{m}{299}$
Question : Select the most appropriate option to improve the underlined segment in the given sentence. If there is no need to improve it, select ‘No improvement required’.

Question : What is the value of the expression $\cos 2 A \cos 2 B+\sin ^2(A-B)-\sin ^2(A+B)$?
Option 1: $\sin (2 A-2 B)$
Option 2: $\sin (2 A+2 B)$
Option 3: $\cos (2 A+2 B)$
Option 4: $\cos (2 A-2 B)$
Correct Answer: $\cos (2 A+2 B)$
Solution : Given, $\cos(2A)\cos(2B)+\sin^2(A-B)-\sin^2(A+B)$ $=\cos(2A)\cos(2B) - [\sin^2(A + B) - \sin^2(A - B)]$ $=\cos(2A)\cos(2B) - [\sin(A + B) + \sin(A - B)][\sin(A + B) - \sin(A - B)]$ Using Identities: $\sin C + \sin D = 2\sin \frac{C+D}{2}\cos \frac{C-D}{2}$ and $\sin C - \sin
