Question : If the simple interest at the same rate of interest on INR 500 for 4 years and INR 700 for 2 years combined, is INR 280, then what is the rate of interest?
Option 1: $9 \frac{3}{17}\%$
Option 2: $6 \frac{5}{17}\%$
Option 3: $8 \frac{4}{17}\%$
Option 4: $7 \frac{3}{17}\%$
Correct Answer: $8 \frac{4}{17}\%$
Solution : P = INR 500 and INR 700 T = 4 years and 2 years R = same for both According to the question, $280 = \frac{\text{500×R×4}}{100}$+$\frac{\text{700×R×2}}{100}$ ⇒ $280 = \frac{\text{2000R}}{100}$+$\frac{\text{1400R}}{100}$ ⇒ $ 280 = \frac{\text{3400R}}{100}$ ⇒ $R = \frac{280}{34} = 8\frac{4}{17}$ Hence, the correct
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’. Often we ourselves are responsible for our ill health.

Question : Directions: Three different positions of the same dice are shown. Find the number on the face opposite to 1.
Option 1: 5
Option 2: 6
Option 3: 2

Question : When one gene pair hides the effect of the other unit, the phenomenon is referred to as:
Option 1: Epistasis
Option 2: Mutation
Option 3: None of the options
Option 4: Dominance
Correct Answer: Epistasis
Solution : The correct option is - Epistasis.

Question : The centroid of an equilateral triangle PQR is L. If PQ = 6 cm, the length of PL is :
Option 1: $4 \sqrt{3} \mathrm{~cm}$
Option 2: $3\sqrt{3} \mathrm{~cm}$
Option 3: $2\sqrt{3} \mathrm{~cm}$
Option 4: $5\sqrt{3} \mathrm{~cm}$
Correct Answer: $2\sqrt{3} \mathrm{~cm}$
Solution : PQ = 6 cm The centroid divides the median in the ratio 2 : 1. Since all the centres lie at the same point L, PL is also the circumradius of Equilateral Triangle PQR. We know, Circumradius of an equilateral triangle = $\frac{\text{Side of
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error".
Most of the members at the meeting felt (1)/ that the group appointed to investigate the case (2)/ were not competent to do the job efficiently. (3)/ No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (3)

The sentence contains an error in the subject-verb agreement. The subject group is singular, so the verb should also be singular.
Were is the incorrect form of the verb; it should be was.
Therefore, the
Question : ABCD is a cyclic quadrilateral and BC is the diameter of the related circle on which A and D also lie. $\angle \mathrm{BCA}=19°$ and $\angle \mathrm{CAD}=32°$. What is the measure of $\angle \mathrm{ACD}$?
Option 1: 41°
Option 2: 38°
Option 3: 40°
Option 4: 39°
Correct Answer: 39°
Solution : Given, $\angle{CAD}=32°$ and $\angle{BCA}=19°$ We know, that the angle formed by the diameter is 90°. ⇒ $\angle{BAC}=90°$ The sum of the opposite angle of a quadrilateral = 180°. ⇒ $\angle{CAD}+\angle{BAC}+\angle{BCA}+\angle{ACD}=180°$ ⇒ $32°+90°+19°+\angle{ACD}=180°$ ⇒ $141°+\angle{ACD}=180°$ ⇒ $\angle{ACD}=180°-141°$ ⇒ $\angle{ACD}=39°$ Hence, the correct answer is 39°.
