Two fifths of the goods were transported in the first time and 78 kg in the second time, accounting for 65% of the total amount. How many kg are there in total? Write the formula
2 out of 1-5 = 3 out of 5
65% = 65 / 100
65-3 / 5 of 100 = 1 / 20
78 * 20 = 1560 (kg)
The total weight of the goods is 1560 kg
