Question : Directions: In the following question, find the odd number pair from the given alternatives.
Option 1: 6
Option 2: 24
Option 3: 64
Option 4: 120
Correct Answer: 64
Solution : Let's check each option – First option: 6; It is a multiple of 6. (6 × 1 = 6) Second option: 24; It is a multiple of 6. (6 × 4 = 24) Third option: 64; It is not a multiple of 6. Fourth option:
Question : Directions: Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term. 169 : 14 :: ? : 16 :: 289 : 18
Option 1: 205
Option 2: 230
Option 3: 225
Option 4: 125
Correct Answer: 225
Solution : Given: 169 : 14 :: ? : 16 :: 289 : 18
Like, (14 – 1)2 = (13)2 = 169 (18 – 1)2 = (17)2 = 289 Similarly, (16 – 1)2 = (15)2 = 225
So, 225 is the
Question : Directions: Study the following histogram of marks in mathematics (out of 50) of students in a class and answer the following question.
If the passing marks in math are 31, the number of students who failed in math is:
Option 1: 10
Option 2: 15
Option 3: 20
Option 4: 25
Correct Answer: 15
Solution : The passing marks are 31, and students who failed are those who scored less than 31. The number of students who failed was 15 and they scored between 25 and 30. Hence, the correct answer is 15.
Question : For any acute angle $\theta, \sin \theta+\sin^2 \theta=1$, then the value of $\cos^2 \theta+\cos^4 \theta=$___________.
Option 1: 0
Option 2: 1
Option 3: 2
Option 4: –1
Correct Answer: 1
Solution : Given: $\sin \theta+\sin ^2 \theta=1$ ⇒ $\sin\theta = 1- \sin^2\theta$ ⇒ $\sin \theta = \cos^2\theta$ $\cos^2 \theta+\cos^4 \theta= \sin\theta + \sin^2\theta = 1$ Hence, the correct answer is 1.
Question : Three numbers are in the ratio 5 : 7 : 12. If the sum of the first and the third numbers is greater than the second number by 50. The sum of the three numbers is:
Option 1: 125
Option 2: 120
Option 3: 95
Option 4: 85
Correct Answer: 120
Solution : Let the first number be 5x, the second number be 7x, and the third number be 12x. According to the question, 5x + 12x = 7x + 50 ⇒ 10x = 50 $\therefore$ x = 5 The required sum of the numbers is: 5x +
Question : Thalassemia is an example of
Option 1: Deletion mutation
Option 2: Point mutation
Option 3: Silent mutation
Option 4: Frame shift mutation
Correct Answer: Frame shift mutation
Solution : The correct answer is Frameshift mutation.
A frameshift mutation is insertion or deletion of nucleotide bases. A genetic code is read in triplets, and in frameshift mutation the altered nucleotide bases are not multiple of three. Examples of frameshift mutation are cystic fibrosis
Question : Directions: Three statements are followed by three conclusions numbered I, II, and III. You have to consider these statements to be true, even if they seem to be at variance with commonly known facts. Decide which of the given conclusions logically follow/s from the given statements. Statements: Some watches are projectors. All projectors are lamps. Some heaters are watches. Conclusions: (I) Some heaters are projectors. (II) Some lamps are heaters. (III) All watches are lamps.
Option 1: Only conclusion II follows
Option 2: None of the conclusions follow
Option 3: Only conclusion I follows
Option 4: Either conclusion I or conclusion III follows
Correct Answer: None of the conclusions follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some heaters are projectors – From the Venn diagram, it is evident that there is no direct relation between heaters and
