A man divided his share between his sons A and B in such a way that the interest received by A at 15% p.a. for 3 years is double the interest received by B at 12% p.a. for 5 years. In what ratio was his share divided?
Here, A = 2B
So,
A*15/100*3 = 2(B*12/100*5)
= A*15/100*3 = 2(B*60/100)
=A*45/100 = B*120/100
=45A = 120B
= 3A = 8B
So, A/B = 8/3
