520 g tiny black marbles are mixed with 580 g of tiny white marbles. Ruhi packed the mixture of tiny marbles into 5 equal packets. How many kg of the mixture are there in each packet? Correct Answer 0.22 kg

Given:

Weight of black marbles = 520 g

Weight of black marbles = 580 g

Number of packets = 5

Calculation: 

Weight of black marbles = 520 g

Weight of black marbles = 580 g

⇒ Total weight = 520 g + 580 g = 1,100 g

⇒ Number of packets = 5

⇒ Weight of each packet = 1,100 g/ 5 = 220 g

1 kg = 1,000g

⇒ 220 g = 220/1000 = 0.22 kg

∴  0.220 kg of the mixture are in each packet.

The correct option is 2 i.e. 0.220 kg
