Total quantity of solution = 12 lts
quantity of salt in it = 25%
quantity of salt in litres
= Total quantity of solution × %quantity of salt in it
=12 ×25%
= 3lts
2 lts evaporated from 12 litres solution...
percentage evaporated
=evaporated quantity/total quantity
=( 2/12 )×100
= 16.67%
Remaining solution
=Total quantity% - evaporated quantity %
= 100 - 16.67 = 83.33%
Quantity of salt remaining will be 3litres ×83.33%
=2.5 ltrs
quantity of salt in it = 25%
quantity of salt in litres
= Total quantity of solution × %quantity of salt in it
=12 ×25%
= 3lts
2 lts evaporated from 12 litres solution...
percentage evaporated
=evaporated quantity/total quantity
=( 2/12 )×100
= 16.67%
Remaining solution
=Total quantity% - evaporated quantity %
= 100 - 16.67 = 83.33%
Quantity of salt remaining will be 3litres ×83.33%
=2.5 ltrs
