No need to make complex its easy.
Because of question ask about result of b.
A = 1210, B = 1210;
2/5*B = 2/5*1210.
= 484.

A=4/5, B=2/5.
Total amount=1210.
Therefore the total amount of B=1210*2/5=484.
So, Ans is 484.
Total amount=1210.
Therefore the total amount of B=1210*2/5=484.
So, Ans is 484.

A+B = 1210 ---- 1.
Given,
4/15*A = 2/5*B.
So A = 3/2*B ----- 2.
From 1 & 2.
3/2B+B = 1210.
5B = 1210*2.
B = 1210*2/5.
B = 484 ------ Answer.

4/15*A = 2/5*B.
A/B = 3/2.
Ratio scale A B Total amount
3 2 5
*242 *242 *242
26 484 1210
So B share is 484.
A/B = 3/2.
Ratio scale A B Total amount
3 2 5
*242 *242 *242
26 484 1210
So B share is 484.
