Answer:
20 Years.
Step-by-step explanation:
Given data:
Total coins in bag = 15
Increment of coins = 5
coins per 100 coin in one year
Years need to increase the coin to 30 in the bag = ?
Solution:
The increment rate is 5%, so the increment per year for 15 coins = 15 * 5/100
= 0.75 coins.
Aladdin needs 15 more coin to have 30 coins in bag,
1 year = 0.75 coin
1/0.75 year = 1 coin.
15/0.75 year = 15 coins.
20 years = 15 coins.
Hence it will take 20 years to fill the Aladdin 30 coins in bag.
