There are 7 crates of apples of the same weight in the mart. After removing 20 kilograms (kg) of apples from each box, the weight of the 7 boxes of apples was equal to the weight of the original 3 boxes of apples. How many kilograms (kg) does one original box of apples weigh?
20 7 [OP_MUL] 7 3 [OP_SUB] [OP_DIV]
var_a = 20
var_b = 7
var_c = var_a * var_b
var_d = 7
var_e = 3
var_f = var_d - var_e
var_g = var_c / var_f
print(int(var_g))
