Answer 1

Let Rohit's salary be x.

according to question ,

x - ( x/5  +  x/4  +  x/3  +  x/15)    =     9000

x  -  [(  12x + 15x + 20x + 4x)  /  60]      =     9000

x    -   51x / 60    =     9000

60x - 51x  /   60       =   9000

9x   /    60      =     9000

x   =     9000   *    60    /    9

x    =    540000  /   9

x     =    60000

Hence,   Rohit's salary be  Rs. 60000.
