Explanation:

Let the amount invested by amar be x and that by Akbar be(5000+x) and Anthony invested (5000+2000+ x)
therefore by formula simple interest = P*R*N/1000
12x/100 +(5000+x)12x/100 +(7000+x)12x/100
we get by solving x = 5000
so the amount invested by Akbar is 5000 +x =10000

Hence, option 2 is the correct answer.
