anne is 10 years old her brother jack will be twice the age as anne in 2 years how old is jack now Ans: Let Jack's age be x now. Anne is 10 years old now. In 2 years, Anne will be 12 years old. In 2 years, Jack will be twice as old as Anne i.e. Jack's age after two years will be 2*12 = 24 years. So, now Jack is 24 - 2 = 22 years old. Hope this helps :)
