The prices of fruits per kg are given below:

Mango: Rs. 80.60

Apple: Rs. 120.50

Watermelon: Rs. 22.50

Grapes: Rs. 110.40

Sneha bought \(3\frac{1}{2}\) kg watermelon, 2 kg mangoes, \(1\frac{1}{2}\) kg apples, and\(\frac{3}{4}\) kg grapes. She gave a Rs. 2000 note to the shopkeeper. How much did she get back?

Given:

The prices of fruits per kg are given below:

Mango = Rs. 80.60

Apple = Rs. 120.50

Watermelon = Rs. 22.50

Grapes = Rs. 110.40

Calculation:

1) 1 kg Watermelon = Rs. 22.50

\(3\frac{1}{2}\) kg Watermelon = 3.5 kg Watermelon 

⇒ The cost of 3.5 kg Watermelon = 3.5 × 22.50

⇒ The cost of 3.5 kg Watermelon = Rs. 78.75

2) 1 kg Mango = Rs. 80.60

⇒ The cost of 2 kg mangoes = 2 × 80.60

⇒ The cost of 2 kg mangoes = Rs. 161.2

3) 1 kg Apple = Rs. 120.50

\(1\frac{1}{2}\) kg apples = 1.5 kg apples

⇒ The cost of 1.5 kg apples = 1.5 × 120.50

⇒ The cost of 1.5 kg apples = Rs. 180.75

4) 1 kg grapes = Rs. 110.40

\(3\over4\) kg grapes = 0.75 kg grapes

⇒ The cost of 0.75 kg grapes = 0.75 × 110.40

⇒ The cost of 0.75 kg grapes = Rs. 82.8

The total cost of all the fruits = The cost of 3.5 kg Watermelon + The cost of 2 kg mangoes + The cost of 1.5 kg apples + The cost of 0.75 kg grapes

⇒ The total cost of all the fruits = Rs. 78.75 + Rs. 161.2 + Rs. 180.75 + Rs. 82.8

⇒ The total cost of all the fruits = Rs. 503.5

Money given to the shopkeeper by Sneha = Rs. 2000

The money that Sneha get back = Money given to the shopkeeper - The total cost of all the fruits

⇒ The money that Sneha gets back = Rs. 2000 - Rs. 503.5

⇒ The money that Sneha gets back = Rs. 1496.5

Hence, the correct answer is Rs. 1496.5
