How it comes?

Anni said:   9 years ago
m * c /(mc + t) * d . Is Answer is 55.2 cm?

Ankit said:   9 years ago
Agree with Anne it's 55.2 cm.

Deepak said:   8 years ago
Yes @Ankit.

55.26 is right answer.

[(m*c)/(mc+t)] * d = 30.215 is the right answer.

Aamir said:   8 years ago
It is 55.25.

Mohamed Emad said:   8 years ago
Stress of steel should be 1250 kg/cm^2 for it to be 30.

Gaja said:   8 years ago
mc/t=n/(d-n).
n= 55.26.
