Question
The Average income of Akash and Bittu is Rs. 31,000. Akash
earns Rs. (p + 5000), while Chirag earns Rs. (2.5p + 500). Given that the average income of Bittu and Chirag is Rs. 40,000, determine Bittu's income.Solution
ATQ,
Akash + Bittu = 31000 * 2 = 62000
Bittu + Chirag = 40000 * 2 = 80000
(Bittu + Chirag) – (Akash + Bittu) = 80000 - 62000
Chirag – Akash = 18000
2.5p + 500 – (p + 5000) = 18000
p = 22500/1.5 = 15000
The income of Akash = 15000 + 5000 = Rs.20000
The income of Bittu = 62000 – 20000 = Rs.42000
