Answer 1

23 TV sets will cost Rs. 644000/-

Answer 2

Answer:-

$\text{Let the cost of 23 T.V Sets be ₹x} \\ \text{The Number of T.V sets and } \\ \text{their cost is in Direct Proportion.} \\ \frac{4}{112000} = \rm\frac{23}{x} \\ \therefore\rm{x} = \frac{112000 \times 23}{4} \\ \therefore\rm{x} = \frac{28000 \times 23}{1} \\ \therefore \rm{x} = 28000 \times 23 \\ \therefore\rm{x} = {644000} \\ \\ \therefore\text{Cost of 23 T.V sets is } \underline{₹644000}$
