A, B and C go shopping together, 1 / 2 of a's money is equal to 1 / 3 of B's money; 3 / 4 of B's money is equal to 4 / 7 of C's money; C is more than a How much did the three spend for 93 yuan? Ask for the column, do not copy
1 / 2 a = 1 / 3 B
3 / 4 B = 4 / 7 C
C-A = 93
The solution is: a = 96, B = 144, C = 189, so a + B + C = 96 + 144 + 189 = 429
So the three spent a total of 429 yuan
