John's savings=J
Bryan Savings=B

1st scenario: 20% of John's savings is \$120 more than 30% of Bryan's savings

1/5J = 3/10B+\$120
J = 3/2B+\$600
B = 2/3J-\$\$400 ....(1)

2nd Scenario: 1/6 of John's saving is \$20 more than Bryan's savings

1/6J = B+\$20...(2)

substitute (1) in (2)

1/6J = 2/3J-\$400+\$20
1/2J=\$380
J=\$380 x 2 = \$760

John's saving was \$760 at first.
