Question

A king wanted to reward his advisor, a wise man of the kingdom. So
he asked the Wiseman to name his own reward. The wise man thanked
the king but said that he would ask only for some gold coins each day
for a month. The coins were to be counted out in a pattern of 1 coin for

the first day, 3 coins for the second day, 5 coins for the third day and so
on for 30 days. Without making calculations, find how many coins will
the advisor get in that month? Mention the property used in finding the answer please.

Answer 1

Answer:

Every day the coins are given in consecutive odd number for 30 days

so according to the property

30x30=900

therefore 900 coins the advisor will get in a month

Answer 2

Answer:

30 ×30=900
