a) 1 : 2
b) 1 : 4
c) 2 : 1
d) 5 : 7
Answer: a
Explanation: Maximum possible number of tables = 6
[1200 × 6 = 7200]
Number of chairs purchased
$$\eqalign{
& {\text{ = }}\frac{{{\text{8100}} – {\text{7200}}}}{{{\text{300}}}}{\text{ = }}\frac{{{\text{900}}}}{{{\text{300}}}}{\text{ = 3}}{\text{}} \cr
& {\text{Required ratio}} = {\text{3}}:{\text{6}} \cr
& {\text{ = 1}}:{\text{2}} \cr} $$
