Correct option is

A

1340 liters

Suppose that,

Selling price P be along X –axis.

And demand of milk D be along Y-axis.

Let y liter milk be sold at Rs x litre.

Consider the given,

Owner sells 980 litre milk at rs 14/litre.

I.e.x1=14,y1=980

And owner sells 1220 litre milk at Rs 16/litre.

i.e.

x2=16,y2=1220

Equation of line passing through (14,980)and(16,122)

So,

(y−980)=16−141220−980(x−14)

⇒y−980=2240(x−14)

⇒y−980=120(x−14)

⇒y=120(x−14)+980

We need to find y when x=17

Putting x=17 in (1)

y=120(x−14)+980

y=120(17−14)+980

y=120×3+980

y=360+980

y=1340

Hence, 1340 like milk may be sold at Rs 17/litre.
