A and B together have Rs. 1210. If of A's amount is equal to of B's amount, how much amount does B have?
Rs. 460
Rs. 484
Rs. 550

4 A = 2 B
15 5

A = 2 x 15 B
5 4

A = 3 B
2

A = 3
B 2

A : B = 3 : 2.

B's share = Rs. 1210 x 2 = Rs. 484.

Let A's amount be x and B's amount be y.
Given:
(4/15)x = (2/5)y.
Solving this, we get x = (3/2)y,
Also given: A + B = 1210.

Substituting.
x = (3/2)y in A + B = 1210, we get (3/2)y + y = 1210.
Simplifying, we get (5/2)y = 1210,
y = (1210 * 2)/5 = 484.

4 * 5a = 2815b
20a = 30b
A:B = 3:2
5-1210
3-726
2-484
B = 484.

4/15A = 2/5B.
a/b = 2/5 * 15/4,
a/b = 3/2,
a:b = 3:2.
3x + 2x = 1210.
5x = 1210.
x = 1210/5.
x = 242.
Sub x value in b.
2(242) = 484.

So the B value is 484.

4x/15 = 2y/5.
x/y = 3/2.
3+2 = 1210.
5 = 1210.
1 = 242.
y = 2y.
2 * 242.
= 484.

B's Share Rs = (1210*2/3) = 484.
A's Share Rs = (1210*4/15) = 323.

A = B.
4/15 = 2/5.
Total amount = 1210,
2/5 * 1210 = 484.

B's share Rs = (1210 * 2/5) = 484.
A's share Rs = (1210 * 4/15) = 323.

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

B's amount = (2/(3+2)) × 1210,
= 484.

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.
