Answer:
let the ratio be '2x', '5x, '3x' .
total money given in form of 1 rupee= 1 into 2x= 2x
total money given in form of 5 rupees= 5 into 5x = 25x
total money given in form of 10 rupees= 3x into 10= 30x
total money given to cashier= 741
ATQ:
2x+25x+30x= 741
57x= 741
x= 741/57=13
2x = 2 into 13 =26
5x= 5 into 13=65
3x= 3 into 13= 39
