The jug contains 4lit of salt water(15% salt). when we
spill 1.5lit , the quantity in the jug becomes 2.5 lit (
the percentage of salt will remain same i.e 15% ):-
= {(15/100*4)/4}*2.5 = 0.375 Lit
when we fill the jug to full capacity, the percentage of
salt will be :
= (0.375/5)*100 = 7.5%
Ans = 7.5 % of salt
