Answer 2

$\blue { Quantity \:of \:1^{st} \: kind \:rice} : \pink { Quantity \:of \:2^{nd} \: kind \:rice} \\= 1.11 : 2.29 \\= 111 : 229$

$\implies Quantity \:of \:1^{st} \: kind \:rice : 66 = 111 : 229$

$\implies Quantity \:of \:1^{st} \: kind \:rice = \frac{ 66 \times 111}{2.29} \\= \frac{7326}{229} \\= 31.99 \: kg$
