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. |

B'S =2/5
A's =3/5
so how A IS EQUAL TO B(A=B)
A's =3/5
so how A IS EQUAL TO B(A=B)

Nice one more method
1210 is total of 2 members
Assume b is x
therefore is A is 1210-x
so 4/15*(1210-x)=2/5*x
4(1210-x)=6x
10x=4840
x=484
1210 is total of 2 members
Assume b is x
therefore is A is 1210-x
so 4/15*(1210-x)=2/5*x
4(1210-x)=6x
10x=4840
x=484

A+B=1210
(4/15)A=(2/15)B
A=(15/4)(2/5)B
A/B=3/2
Take it as A/3=B/2
Adding denominators 5P.
So,5P=1210
P=242
B's Amount is 2P i.e,2(242)=484
(4/15)A=(2/15)B
A=(15/4)(2/5)B
A/B=3/2
Take it as A/3=B/2
Adding denominators 5P.
So,5P=1210
P=242
B's Amount is 2P i.e,2(242)=484

Can anyone please explain, how u can find out the ration of A & B because in question they only tell that if of A's amount is equal to of B's amount. and also explain meaning of this line and how u can find that (4/15)A=(2/15)B .

What is the significance of finding ratio here. As B's share is calculated directly further in answer. Please explain.

Through ratio share can be divided accordingly as A:B=3:2 B' SHARE will be 2/5*1210=484.
