Solution(By Apex Team)
Average cost: Rs. 1.30 per kg.
And,
$\begin{array}{l}\text{Hence, ratio of 1.27, 1.29 and 1.32}\\
\text{⇒ n1 : n2 : n3 = 2 : (2 × 3) : 3}\\
\text{⇒ n1 : n2 : n3 = 2 : 6 : 3}\end{array}$
And,
$\begin{array}{l}\text{Hence, ratio of 1.27, 1.29 and 1.32}\\
\text{⇒ n1 : n2 : n3 = 2 : (2 × 3) : 3}\\
\text{⇒ n1 : n2 : n3 = 2 : 6 : 3}\end{array}$
