A body cools from 60∘C to 50∘C in 10 minutes. If the room temperature is 25∘C and assuming Newton's cooling law holds good, the temperature of the body at the end of the next 10 minutes is:45oC42.85oC40oC38.5oC

A body cools from $60^{\circ} C$ to $50^{\circ} C$ in $10$ minutes. If the room temperature is $25^{\circ} C$ and assuming Newton's cooling law holds good, the temperature of the body at the end of the next $10$ minutes is:
$45^{o} C$
${42.85}^{o} C$
$40^{o} C$
${38.5}^{o} C$
