By solving 4A/15 and 2B/5, we will get the ratio 3:2.

So, total 5 parts,
Let's find 1 part that is 1210/5 = 242.
Then for B, the ratio is 2, so multiply it by 2 = 484.

4/15A = 2/5B.
a/b = 2/5 * 15/4.
a/b = 3/2.
a:b = 3:2.

Then 3x + 2x = 1210.
5x = 1210.
x = 1210/5.
x = 242.

Then Sub x value in b.
B = 2(242) = 484.
A = 3(242) = 726.

(4/5)A = (2/5)B,
then A/B = 3/2,
or A:B = 3:2.

B's amount = (2/(3+2)) × 1210,
= 484.
