Explanation:

From the question we are told that:

Table for price per Kg

Watermelon Rs 18.50

Cherry Rs 72

Grapes Rs 120.60

Apples Rs 78.40

Karan Bought:

412 kg watermelon

1 kg 200g cherries

250 g grapes

134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

`\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))`

`\sum (P* W)=27374289.78`

Therefore the Amount of Money he gets back is

`X=500-\sum (P* W)`

`X=-2.74*10^(-7)Rs`

Therefore

He owes the shop keeper 2.74 million Rs
