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. |

A + B = 1210.
Now find the value of B?
4/15 A = 2/5 B.
A = (2/5 * 15/4) B.
==> A = (3/2) B.
ratio is A : B = 3:2 ==> ratio of A is 3 and ratio of B is 2.
A + B = 1210 // this formula Apply the A value,
(3/2) B + B = 1210 // ratio of B is 2 so B is replace 2.
(3)B + 2 = 1210 * 2,
(3)B + 2 = 2420,
5(B) = 2420,
B = 2420/5,
B = 484.

How will you find B's share directly to 1210?

A+B Total value is R.s 1210.
So Directly we can Calculate B share,
Acc to the question B share 2/5,
Thus 1210 of 2/3,
= 1210 * 2/3,
= 484 RS.
