a question that appeared from my exam i am remembering this with my best ability!


Names differ


Tom had $200 more than Harry. In the afternoon, Tom gave some money to Harry. The ratio to the amount he had left to the amount he gave away is 2:3. In the evening, Harry gave some money to Tom. The ratio of the amount he had left to the amount he gay away is 3:1. In the end, Harry had $200 more than Tom. How much did Tom have at first?


Thanks for your help!

When Tom gave sone money to Harry
Tom : 5u - 3u = 2u
Harry : 5u - $200 + 3u = 8u - $200

When Harry gave some money to Tom
Harry : (8u - $200) - (2u - $50) = 6u - $150
Tom : 2u + (2u - $50) = 4u - $50

(6u - $150) - ( 4u - $50) = $200
2u = $200 + $150 - $50 = $300
1u = $150

Amt Tom had at first = 5u = 5 x $150 = $750
