We are given information linking six individuals (Raj, Rohit, Rachit, Rajat, Rishu, Rinku) with specific salaries ($1000, 2000, 2500, 3000, 3500, 4000$) and favorite cars (P, Q, R, S, T, U). We need to find who earns $3000.
Let's track the assigned salaries:
The remaining salaries to be assigned are $1000$ and $3000$. The remaining individuals are Raj and Rohit.
Given that Rohit's salary is not $1000$, he must earn the other available salary, which is $3000$. Consequently, Raj earns $1000$.
The clue "The one who likes car Q gets a salary of 3000" implies Rohit likes car Q.
Rohit is the person who gets a salary of $3000$.
Below is given a figure, in which a horse is placed on one of the boxes in a square grid of size $5 \times 5$. The horse can move in either of the following ways in a single move:
(i) two boxes to either left or right side and one box to either up or down side
(ii) two boxes to either up or down side and one box to either left or right side
(iii) the horse cannot step on a grey box. The horse has to stay within the grid and any move to out of the grid is NOT legal.
How many white boxes are there which cannot be covered by horse within 3 moves?
