Vidushi gives x Rs to (y+5) people
Sanya gives (x+1) Rs to y people
each person gives 100 Rs
100=2*2*5*5
100=4*25 and
100=5*20
Vidushi gives 4 Rs to 25 people each for a total of 100 Rs
Sanya gives 5 Rs to 20 people each for a total of 100 Rs
25+20=45 people received Rs
write 100 using prime factorization; use factor trees or upside down division
