The correct option is A p = 24q = 21
Given,
Cost of 2 oranges is ₹8.
We know that more the number of oranges, more the cost.
So, Number of oranges(x)∝Cost(y)
∴ x1y1 = x2y2
Given,
x1 = 2 oranges
y1 = ₹8
x2 = 6 oranges
and y2 = p = cost of 6 oranges
⇒ y2 = x2 × y1x1
⇒ p = 6 × 82 = ₹24
Again,
x1 = 2 oranges
y1 = ₹8
y2 = ₹84
and x2 = q = no. of oranges
⇒ x2 = x1 × y2y1
⇒ q = 2 × 848 = 21 oranges
