Question

Aladdin has 15 gold coins in his magic bag. The Genie tells him that for every 100 gold coins he has in his magic bag, he will get 5 extra gold coins every year. How many years later will Aladdin have 30 gold coins in his bag?

Answer 1

20 Years.

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.
