You have to recognise that by giving away money to Jane,

1. Kenneth loses a sum of money.
2. Jane gains the same sum of money.

From "Kenneth had \$90 more than Jane" to "Jane had \$30 more than Kenneth", there is a total "money flow" of \$120.

So Kenneth must have given away \$60 to Jane. The order of sequence is in the following two-step story.

1. After Kenneth gives away the \$60 (but Jane has not accepted the money yet), Kenneth has \$30 more than Jane.

2. After Jane accepts the \$60, Jane has \$30 more than Kenneth.

Makes sense, right?

So Kenneth gives \$60 to Jane. This corresponds to 60% of his money.

60% --> \$60
1% --> \$1
100% --> \$100

So Kenneth starts out with \$100.
Jane starts out with \$10.

You can check that the answers are true by making sense of the story using these numbers.
