There were some starfruits in 3 bags, H, J and K. 25% of the number of starfruits in Bag H was equal to 10% of the number of starfruits in Bag J. The number of starfruits in Bag K was 70% of the total number of starfruits. After Justin removed 10% of the starfruits in Bag K, there were 582 more starfruits in Bag K than in Bag J. In the end, how many starfruits should be transferred from Bag J to Bag K so that the number of starfruits in Bag H would be the same as Bag J?

710The total number of starfruits in Bag H and Bag J is the combined repeated identity. Make the total number of starfruits in Box H and Bag J the same. LCM of 7 and 3 = 21
Number of starfruits removed from Bag K
=
10100 x 49 u
= 4.9 u
Number of starfruits left in Bag K
= 49 u - 4.9 u
= 44.1 u
Number of more starfruits in Bag K than Bag J
= 44.1 u - 15 u
= 29.1 u
29.1 u = 582
1 u = 582 ÷ 29.1 = 20

Number of starfruits to be transferred from Bag J to Bag K so that the number of starfruits in Bag H would be the same as Bag J.
= 15 u - 6 u
= 9 u
= 9 x 20
= 180
Answer(s): 180
