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. |

Listen @Yogesh.
Take A=3x and B=2x.
5x= 1210 => x= 242.
Then B= 2 * 242= 484 Ans.

A4/15 = B2/5.
A/B = 3/2,
5 = 1210,
1 = 242,
B = 242 of 2 = 484.
A/B = 3/2,
5 = 1210,
1 = 242,
B = 242 of 2 = 484.

A+B=1210
(4/15)A=(2/5)B
2A=3B
Therefore, A=(3B)/2
and substituting, (3B/2)+B=1210
and hence, 5B=2420 => B=484 Rs.
(4/15)A=(2/5)B
2A=3B
Therefore, A=(3B)/2

Nothing ya. just simple.
4/15=2/5
How it will bcom equal ? just c the denominator.
4/15
If you multiply 5 by 3 u will get 15 do it in the numerator also so it becoms 6/15 for B. calculate ratio for B now 1210*6/15= 484
solution.
4/15 = 2/5
4/15 = 2/5*3/3
4/15 = 6/15
therefor A:B 4:6
1210 * 6 / 15
484
4/15=2/5
How it will bcom equal ? just c the denominator.
