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?
of A's amount is equal to of B's amount, how much amount does B have?
Answer: Option
Explanation:
| 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.

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

A = 3/2B.
=> A/B = 3/2 Divide symbol can be considered as Ratio, So,
=> A:B = 3:2.
When it comes to the ratio 3:2.
The ratio value can be added to get the whole amount.
Here, the whole amount can be represented as 5 parts(Adding 2+3 = 5).
And according to the ratio (A:B = 3:2), B equals to 2/5 part of the whole amount(1210), which can be represented as;
2/5(1210) = 484.

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

Why should we have to find a : b?
Here we can directly multiply the 2/5*1210. Right?
