Heat And Thermodynamics

If some heat is given to a metal of mass 100 g , its temperature rises by $20^{\circ} \mathrm{C}$. If the same heat is given to 20 g of water, the change in its temperature (in ${ }^{\circ} \mathrm{C}$ ) is (The ratio of specific heat capacities of metal and water is $1: 10$ )
