Question

Raj sold 21 tables in a day. He told his father, "My earnings at end of the day are Rs 400000/-. The average earning from the first 11 tables I sold was Rs 20000/-". What were his average earnings from the remaining tables?

Answer 1

Answer:

₹18000

Step-by-step explanation:

Average earning made by first 11 tables = ₹20000

Total earning at the end of day(21 tables) = ₹400000

Total cost of 11 tables = 20000 * 11 = ₹220000

Cost of the rest(21 - 11 = 10 tables) = 400000 - 220000 = ₹180000

Average earning from remaining tables = $\frac{Cost}{Number \ of \ tables}$

$\frac{180000}{10} = 18000$

Therefore

Average earning from the remaining tables is ₹18000
