let the constant of ticket ratio be x so it becomes 3x ,2x and x
so rs spend on buying 20 rs ticket = cost * no. of tickets = 20*3x = 60x
similarly rs spend on buying 80 rs tickets and 190 rs tickets are 160x and 190x respectively
now 160x + 60x + 190x = 2460
410x = 2460
x = 2460/410 = 246/41 = 6
so she purchased 6*3+2*6+6= 18+12+6 = 36 tickets
so rs spend on buying 20 rs ticket = cost * no. of tickets = 20*3x = 60x
similarly rs spend on buying 80 rs tickets and 190 rs tickets are 160x and 190x respectively

410x = 2460
x = 2460/410 = 246/41 = 6
