The ratio between Sarah and Emily is 6:4, or 3:2. If Sarah gets $15 more than Emily, then Sarah gets $45 and Emily gets $30.

Then the ratio between Pritam and Sarah is 3:6, or 1:2; Since Sarah gets $45, Pritam gets half as much, $22.50.

Pritam    :    Sarah    :    Emily
   P      :   E+15      :     E
   3      :    6        :     4

6%2F4=%28E%2B15%29%2FE
3%2F2=%28E%2B15%29%2FE
3E=2%28E%2B15%29
3E=2E%2B30
E=30


Use that to revise the ratio information:
Pritam    :    Sarah    :    Emily
   P      :     45      :     30
   3      :    6        :     4

More than one way to go for finding P.
P%2F45=3%2F6
P%2F45=1%2F2
P=45%2F2
highlight%28P=22.50%29
