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. |

The problem how 2/5*(1210)comes?
a+b = 1210 and now we got ratio a/b = 3/2,
So,add +1 both side,
a/b+1=3/2+1
a+b/b = 5/2.
Now b=2/5(a+b) = 2/5(1210) = 484.
a+b = 1210 and now we got ratio a/b = 3/2,
So,add +1 both side,
a/b+1=3/2+1
a+b/b = 5/2.
Now b=2/5(a+b) = 2/5(1210) = 484.

(4/15)A = (2/5)B.
Solve it and you will get A:B = 3:2.
Solve it and you will get A:B = 3:2.

This can be done cery easily by simple algebra. tTher are two conditions,
First, A+B =1210.
Second,
A* 4/15 = B* 2/5.
A= B* 2/5 *15/4
A = 3/2 B. Put this value of A in first condition,
We get,
3/2 * B + B =1210.
5/2 *B =1210.
B =1210 * 2/5.
B =484.
First, A+B =1210.
Second,
A* 4/15 = B* 2/5.
A= B* 2/5 *15/4
A = 3/2 B. Put this value of A in first condition,
We get,
3/2 * B + B =1210.
5/2 *B =1210.
B =1210 * 2/5.
B =484.

To find B=?.
B = 1210*2/5.
B = 2420/5.
B = 484,
B = 1210*2/5.
B = 2420/5.
B = 484,

Can you give solution for this problem?
A vessel of 125 lts. Capacity is full of pure milk on the first day 2/5 of the milk is drawn and filled with water, on the second day 2/5 of the mixture is drawn and filled with water, and again the same thing is done on the third day. Find the quantity of milk at the end?
