A sum of Rs. 1360 has been divided among A, B and C such that A gets 
of what B gets and B gets 
of what C gets. B's share is:
of what B gets and B gets of what C gets. B's share is:
Answer: Option
Explanation:
Let C's share = Rs. x
| Then, B's share = Rs. | x | , A's share = Rs. |  |
2 | x | x |  |
= Rs. | x |
| 4 | 3 | 4 | 6 |
 |
x | + | x | + x = 1360 |
| 6 | 4 |
 |
17x | = 1360 |
| 12 |
| x = |
1360 x 12 | = Rs. 960 |
| 17 |
| Hence, B's share = Rs. | |
960 | |
= Rs. 240. |

Lets we do this problem in ratio method.
Given B gets 1/4 what of what c gets & A gets 2/3 of what B gets,
Lets c gets x, then B = x/4, then a gets 2/3(x/4) = x/6.
Hence A: B: C = x/6 : x/4 : x.
Hence A: B: C: = 2:3:12.
There fore the share of B is 3/17(1360) = 240.
Given B gets 1/4 what of what c gets & A gets 2/3 of what B gets,
Lets c gets x, then B = x/4, then a gets 2/3(x/4) = x/6.
Hence A: B: C = x/6 : x/4 : x.
Hence A: B: C: = 2:3:12.
There fore the share of B is 3/17(1360) = 240.

let C be x.
//B gets 1/4 of what C gets means(of means multiply).
//What is C, C=x,
B=1/4 * C i.e.(1/4 * x) =>x/4.
// A gets 2/3 of what B gets means.
// What is B, B=x/4.
A=2/3*B i.e.(2/3 * x/4) => x/6.
Adding all means A + B + C.
x/6 + x/4 + x.
Taking an LCM of 6,4 i.e. 12.
This means 2x+3x+12x/12 => 17x/12.
=>17x/12=1360 => x= 1360*12/17 i.e.=> x= 960.
Put In B Share(means x/4) i.e. =>960/4=240.
Got it.
//B gets 1/4 of what C gets means(of means multiply).
//What is C, C=x,
B=1/4 * C i.e.(1/4 * x) =>x/4.
// A gets 2/3 of what B gets means.
// What is B, B=x/4.
A=2/3*B i.e.(2/3 * x/4) => x/6.
Adding all means A + B + C.
x/6 + x/4 + x.
Taking an LCM of 6,4 i.e. 12.
This means 2x+3x+12x/12 => 17x/12.
=>17x/12=1360 => x= 1360*12/17 i.e.=> x= 960.
Put In B Share(means x/4) i.e. =>960/4=240.
Got it.

To say the truth I didn't understand any of the methods. Can any one explain it clearly.

Every thing is ok but how can we calculate the 17?

How come B is equal 1/4(X) ?

A:B = 2:3.
B:C = 1:4.
A:B:C = 2:3:12.
Total parts = 2+3+12+17 parts.
17 parts = 1360.
B's share is 3 parts.
Then (1360*3)/17.
= 240.
B:C = 1:4.
A:B:C = 2:3:12.
Total parts = 2+3+12+17 parts.
17 parts = 1360.
B's share is 3 parts.
Then (1360*3)/17.
= 240.

This is a reversible equation
Here 1=X
c=1,b=1/4 & a=1/6
c+b+a=1360
X*(1+1/4+1/6)=1360
X *((12+3+2)/12)= 1360
By solving we get b=240.

I have got a simple substitution way of solving
A+B+C=1360
A=2/3B , B=1/4C(C=4B as we need B's share)
2/3B+B+4B=1360
B=240
A+B+C=1360
A=2/3B , B=1/4C(C=4B as we need B's share)
2/3B+B+4B=1360
B=240
