Answer» Answer: The answer Reena's present AGE = 10 yearsStep-by-step explanation: => Let Reena present age be x years. => Hence, her mother present age = ( x + 20 ) [ As reena is 20 years YOUNGER, her mother age is 20 years more than her age ] => After 10 years, => Reena age will be = ( x + 10 ) years and her mother age will be [ ( x + 20 ) + 10 ] years => According to the PROBLEM, => Reena mother will be 2 times as old as Reena after 10 YEAR. => ( x + 20 ) + 10 = 2 ( x + 10 ) => x + 20 + 10 = 2x + 20 => x + 30 = 2x + 30 => 2x + 20 = x + 30 => 2x = x + 30 - 20 => 2x = x + 10 => 2x - x = 10 => x = 10 :- Reena present age is 10 years. Check :- Reena present age = 10 years Reena mother age = 30 years After 10 years, Reena age = 10 + 10 = 20 years After 10 years, mother age = 30 + 10 = 40 years and 40 is twice of 20 Thus, the answer Reena present age = 10 years is correct. I hope this will help you dear.. Always stay safe and stay HEALTHY.. |
