there are 20 cm , 21 cm , 22 cm , 23 cm , 24 cm , 25 cm rods of quantities 23 , 64 , 32 respectively . find average of this data .
n0 = 20.0
n1 = 21.0
n2 = 22.0
n3 = 23.0
n4 = 24.0
n5 = 25.0
n6 = 23.0
n7 = 64.0
n8 = 32.0
t0 = n3 + n7
t1 = n0 * n3
t2 = n1 * n3
t3 = n2 * n7
t4 = n3 * n7
t5 = n4 * n8
t6 = n5 * n8
t7 = t1 + t2
t8 = n8 + t0
t9 = t7 + t3
t10 = t8 * 2.0
t11 = t9 + t4
t12 = t11 + t5
t13 = t12 + t6
answer = t13 / t10
print(answer)
