Step-by-step explanation:
Given:-
The share of A is 3/7th of the total share of B and C.and total share of A, B and C is Rs. 1400.
To find:-
Find the share of A.
Solution:-
Total share of A , B and C = Rs. 1400
A + B + C = 1400 ------(1)
Share of A = 3/7th of the total share of B and C
=>A = (3/7)(B+C)
=>B+C = 7A/3 --------(2)
On Substituting the value of B+C in (1) then
=>A+(7A/3)=1400
=>(3A+7A)/3 = 1400
=>10A/3 = 1400
=>10A = 1400×3
=>10A = 4200
=>A = 4200/10
=>A = 420
Answer:-
The share of A for the given problem is Rs. 420
