Question
Average salary of 25 employees is ₹40,000. Two new
employees with salaries (p + 9000) and (p - 3000) join, and the average becomes ₹41,000. Find (p - 20,000).Solution
27 × 41,000 − 25 × 40,000 = p + 9000 + p − 3000
2p + 6000 = 1,107,000 − 1,000,000 = 107,000
2p = 101,000
p = 50,500
p − 20,000 = 30,500
