Make me Brillanst Answer

Step-by-step explanation:

To calculate the weighted average, we need the price per tonne and the corresponding quantity for each observation. From the given information, we have:

Observation 1:

Price per tonne: ₹45.60

Tonnes purchased: 3

Observation 2:

Price per tonne: ₹46.23

Tonnes purchased: 135

Observation 3:

Price per tonne: ₹50.70

Tonnes purchased: 40

Observation 4:

Price per tonne: ₹25

Tonnes purchased: ?

To find the missing tonnes purchased in Observation 4, we need more information. Without the value for tonnes purchased, we cannot accurately calculate the weighted average or determine the simple average.

Therefore, based on the given information, we cannot determine the simple average or the correct option (a), (b), (c), or (d). We also need the missing value for tonnes purchased in Observation 4 to calculate the weighted average.

Step-by-step explanation:
