# What is the new average of price per kg:

The average price per kg of rice at 10 different places was 4.85. After a week, the price per kg was increased by 20 paisa at 3 places and decreased by 10 paisa at one place.

- 4.88
- 4.86
- 4.90
- 5.35

**Answer: (3) 4.90**

**Solution:-**

Let price at each place be Rs. X

then total price = 10 X = 48.5

The price at 3 places = (X + 0.2)

Total price at 3 places = (3 X + 0.6)

The price at 1 places = (X – 0.2)

The price at remaining 6 places =Xx

Total price at 6 places = 6 X

New average = [3 X + 0.6 + X – 0.2 + 6 X]/10

= [10 X + 0.4]/10

= [48.5 + 0.4]/10

= Rs 4.89

Hence, the correct answer is option (3) 4.90
