Answer 1

Answer:

48,000

Step-by-step explanation:

Sum = 12,000

It becomes double(24,000) in 5 years.

So, in 20 years, which is 15 years later, it will become 4 times more than the sum. Which means-

12,000*4=48,000

Answer 2

12000 double in 5 years

after 5 years = 24000

after 5 years = 48000

after 5 years =96000

after 5 years = 1,92,000

after 20 years it will be 192000
