There are apples, bananas and persimmons in the fruit shop. The number of apples is 4 times the number of bananas, and the number of persimmons is 3 times the number of bananas. If the sum of apples and persimmons is 210, how many bananas are there?
210 4 3 [OP_ADD] [OP_DIV]
var_a = 210
var_b = 4
var_c = 3
var_d = var_b + var_c
var_e = var_a / var_d
print(int(var_e))
