let A=tank containing Amul milk 130L
and S=tank containing Sudha milk 180L
now suppose x L milk from A ans S is drawn
after mixing milk as perthe condition, it gives same proportion of Amul milk in both the tanks
in A proportion of Amul milk=(130-x)/130
in S proportion of Amul milk=(x)/180
solve this for x
x=(130*180)/310
x=75.48

Ans:75.48
Take Option to solve the question...
130-75.48=54.52
180-75.48=104.52
2x for First quality
x for second quality
54.52=50
104.52=100
2x/x=100/100=1 So two types of milk same price
