Question

15. The average income of A and B Rs. 50, B and C Rs. 60, A and C Rs. 58. Find the income of B ?​

Answer 1

Answer:

Let monthly income of A $=a$

monthly income of B $=b$

monthly income of C $=c$

$a+b=2×5050~\cdots (1)\\b+c=2×6250~\cdots (2)\\a+c=2×5200~\cdots(3)$

$(1)+(3)-(2)$

$\Rightarrow a+b+a+c-(b+c)=2×5050+2×5200-2×6250\\\Rightarrow 2a=2(5050+5200-6250)\\\Rightarrow a=4000$

That is, monthly
