Answer: There are 20 biscuits in larger meal.
Step-by-step explanation:
Given: Previous quantity of chicken = 6
In larger meal it becomes 15.
Previous quantity of biscuit = 8
Let [tex]x[/tex] = quantity of biscuit in larger meal.
If the ratio remains the same, then the direct equation to the relation between x and y is given by :
[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
Now,
[tex]\dfrac{x}{8}=\dfrac{15}{6}\\\\\Rightarrow\ x=\dfrac{15}{6}\times8=20[/tex]
Hence, there are 20 biscuits in larger meal.
