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.

(4/5)A = (2/5)B,
then A/B = 3/2,
or A:B = 3:2.
B's amount = (2/(3+2)) × 1210,
= 484.
then A/B = 3/2,
or A:B = 3:2.
B's amount = (2/(3+2)) × 1210,
= 484.
