SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
I. Let Rohan's and Sachin's salaries be ₹$3x$ and ₹$4x$ respectively. Then, $3x+4x=14000 \Rightarrow 7x=14000 \Rightarrow x=2000$. $\therefore$ Rohan earns ₹6000 per month. II. Let Rohan's salary $=₹x$. Then, Sachin's salary $=₹(x+2000)$. $x+(x+2000)=14000 \Rightarrow 2x=12000 \Rightarrow x=6000$.
