Compare the following ratios

60g:50g : : 180ml : 150ml

24km : 36 km = 28m : 54

I don't understand because the units are different. Please explain soon as i have my exams. Thanks

1.  60 g : 50g :: 180ml : 150 ml

g and g & ml and ml are been canceled

The digits left = 60,50,180,150

Extreme terms = 60 * 150 = 9000

Middle or means terms = 50 * 180 = 9000

Since , LHS = RHS

60 g : 50 g :: 180 ml : 150 ml is correct.

2.     24 km : 36 km = 28 m : 54

I also have doubt in this question . But I think that there must be some unit after 54.If it is like this,then the question is very easy to solve.
