Correct Answer: 2 : 1
Solution :
Let the cost price (CP) of sugar A be Rs. 30 and sugar B be Rs. 45.
Let the CP of the mixture be Rs. $x$.
Now, $\frac{120x}{100}$ = 42
$\therefore x$ = 35
Using the concept of alligation we have,
Required ratio = (Higher value – Mean value) : (Mean value – Lower value)
= (45 – 35) : (35 – 30) = 10 : 5 = 2 : 1
Hence, the correct answer is 2 : 1.
