Average salary of M,N and S is 4000
\therefore \dfrac {M \, + \, N \, + \, S}{3} \, = \, 4000 -eq 1
Similarly, \dfrac{N \, + \, S \, + \, P} {3}
Salary of P = 6000
\therefore N + S = (3 \, \times \, 5000 - P)
= 15000 – 6000 = 9000
using N + S value in above eq 1
M + 9000 = 12000 ; =) M = 3000
Now \dfrac {M} {P} \, = \, \dfrac {3000} {6000} \, = \, \dfrac {1}{2} = 50 \,\%
Correct option is: 50 %

Question 04.
Humans are naturally compassionate and honest. In a study using strategical placed wallets that appear “lost”, it was found that wallets with money are more likely to be returned than wallets without money. Similarly, wallets that had a key and money are likely to be returned than wallets with the same amount of money alone. This suggests that the primary reason for this behavior is compassion and empathy.
Which one of the following is the CORRECT logical inference based on the information in the above passage?
Previously Asked in : Gate ME-forenoon season 2022 ||
Answer is: Wallets with a key are more likely to be returned because people relate to suffering of others
Detailed Explanation
Question 05.
A rhombus is formed by joining the midpoints of the sides of a unit square.
What is the diameter of the largest circle that can be inscribed within the rhombus?
Previously Asked in : Gate ME-forenoon season 2022 ||
Detailed Explanation
From question data, the diagram is
we can clearly say that,
Diameter of circle = Side of rhombus
\therefore d = \sqrt{ \left(\dfrac {1}{2} \right)^2 \, + \, +{\left (\dfrac{1}{2} \right)}^2}
\dfrac{\sqrt{2}} {2} = \dfrac {1}{2}
Correct option is: \dfrac {1} {\sqrt{2}}
