in 16 years time jim will be 3 times his current age .How old will jim be in 4 years time

Answer 1

Let the Jim's age be x.

After 16years :

Jim's age =x+16.

ATQ,

x+16=3x

16=3x-x

16=2x

x=8.

Hence, Jim's present age is 8years.

After 4 years Jim will be 8+4=12 years.


Hope it helps.

Answer 2

Let Jim's present age be a years

According to question

Age of jim After 16 years = 3 × His present age

=> a + 16 = 3a

=> 16 = 3a - a

=> 2a = 16

=> a = 8

Jim's present age = 8 years

Jim's age after 4 years = 8 + 4 = 12 years.
