(4/15)A = (2/5)B.

Solve it and you will get A:B = 3:2.

This can be done cery easily by simple algebra. tTher are two conditions,
First, A+B =1210.

Second,
A* 4/15 = B* 2/5.
A= B* 2/5 *15/4
A = 3/2 B. Put this value of A in first condition,
We get,
3/2 * B + B =1210.
5/2 *B =1210.
B =1210 * 2/5.
B =484.
