Solution
The correct option is A 8:3
For two or more ratios, if we take antecedent as product of antecedents of the ratios and consequent as product of consequents of the ratios, then the ratio thus formed is called mixed or compound ratio.
∴ Required compound ratio = (2 x 3 x 5 x 4) : (3 x 5 x 1 x 3)
= 120 : 45 = 8 : 3
Hence, the compound ratio of 2:3, 3:5, 5:1 and 4:3 is 8:3
