An object kept in a large room having air temperature of $\displaystyle 25$°C takes $\displaystyle 12$ minutes to cool from $\displaystyle 80$°C to $\displaystyle 70$°C.
The time taken to cool for the same object from $\displaystyle 70$° to $\displaystyle 60$°C would be nearly,
Official answer
(4)
$\displaystyle 15$ min
