Correct Answer: TK 81000
Explanation:
Let, Dr. Y’s per patients charge = .1:
Dr. X’s patients charge = $\frac{x \cdot 3}{2}$
Now, Dr. Y’s monthly income = x x 16 x 30 = 480x
And Dr. X’s, monthly income =$\frac{x \cdot 3 \cdot 12 \cdot 30}{2}$ = 540x480x = 72,000
x = 150
The monthly income of Dr. X = (540 x 150) = ‘TK. 81,000
