Question : Directions: Select the figure from among the given options that can replace the question mark (?) in the following series.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : According to the given question figures – 1. The number of triangles in each figure is a prime number in continuous increasing order. 2. In the first figure we have 2 triangles so in the next figure number of triangles is 3, 5, 7, and 11.
Question : In 1785, who used the calibrated torsion balance to measure the force between electric charges?
Option 1: R. A. Millikan
Option 2: Hans Christian Oersted
Option 3: John Michell
Option 4: Charles-Augustin de Coulomb
Correct Answer: Charles-Augustin de Coulomb
Solution : The correct option is Charles Augustin de Coulomb.
In 1785, the French physicist Charles-Augustin de Coulomb used a calibrated torsion balance to experimentally investigate and measure the force between electric charges. Coulomb's work laid the foundation for understanding electrostatic forces and formulating
Question : Directions: Select the related number from the given alternatives. I : 9 :: ? : 13
Option 1: J
Option 2: M
Option 3: L
Option 4: K
Correct Answer: M
Solution : Given: I : 9 :: ? : 13
Like, I : 9→I is the 9th letter of the English alphabet. Similarly, for (?) : 13→M is the 13th letter of the English alphabet.
So, M is related to 13. Hence, the second option is correct.
Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: I. Some red is a mouse. II. No grey is a mouse Conclusions: I. All red is grey. II. No mouse is grey.
Option 1: Only conclusion I follows
Option 2: None of the conclusions follow
Option 3: Both conclusions I and II follow
Option 4: Only conclusion II follows
Correct Answer: Only conclusion II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): All red is grey – As shown, in the diagram above it is clear that there is no definite relation between red
