the sum of money is shared among 4 brothers. the eldest receives 2/7 of it and the next receives 3/5 of the remainder. If the youngest brother receives $120 each, find the sum of money shared.

Total = $X.
Oldest = $2x/7.
2nd Oldest = 3/5 * 5x/7 = $3x/7.
3rd = $x/7 = $120.
4th = $x/7 = $120.
x/7 = 120
X = $840.
