clear my doubt pls (Question: 128770.0 )

pls explain this ..is there any other method to solve this

Question:
Rs.7800 are distributed among A, B and C. The share of A is \(\cfrac{3}{4}\) share of B and share of B is \(\cfrac{2}{3}\) of the share of C, then find the difference between share of B and C.
Options:
A) Rs.1000
B) Rs.1100
C) Rs.900
D) Rs.1200
E) None of these
Solution:

Ans (d) A : B = 3 : 4

B : C = 2 : 3

A : B : C

3 : 4 → 4

2 ← 2 : 3

6 : 8 : 12

A : B : C = 6 : 8 : 12

= 3 : 4 : 6

If (3 + 4 + 6) = 7800

13 = 7800

1 = 600

Difference between B and C = 2 = 2 × 600

= 1200
