⟩ Jalia is twice older than qurban. If jalia was 4 years younger, Qurban was 3 years older their difference between their ages is 12 years. What is the sum of their ages?a) 67b) 57c) 36d) none
very simple logic is take julia as 2x
qurban as x
then]
(2x-4)-(x+3)=12
so x=19
so the present sum of ages is 38+19=57
