One kilogram of ice at $0^{\circ} \mathrm{C}$ is mixed with one kilogram of water at $80^{\circ} \mathrm{C}$. The final temperature of the mixture is (Take specific heat of water $=4200 \mathrm{~kJ} / \mathrm{kg}-{ }^{\circ} \mathrm{C},$ Latent heat of ice $\left.=336 \mathrm{~kJ} / \mathrm{kg}\right)$

• Correct answer
  A

  $0^{\rho} \mathrm{C}$
• B

  $40^{\circ} \mathrm{C}$
• C

  $50^{\circ} \mathrm{C}$
• D

  $60^{\circ} \mathrm{C}$

Hence, the correct answer is option: 'A'.
