Neha's mother was four times her age 12 years ago. She will be twice as old as Neha 12 years from now. What is the present age of Neha's mother ?  Pick.
A) 60 years
B) 33
C) 77
D) 66
E) 101
Explanation:   Let Neha's present age be 'x' years.   Her age 12 years ago = (x – 12) years   Therefore, her mother's age 12 years ago = 4(x – 12)   Her mother's present age = 4x – 48 + 12 = 4x – 36   Neha's age after 12 years = x + 12   Her mother's age after 12 years = 4x – 36 + 12 = 4x – 24   4x – 24 = 2(x + 12)   4x – 2x = 24 + 24   x = 24   Therefore, Neha's present age = 24   Her mother's present age = 4x – 36 = 4(24) – 36 = 60 years   60 yearsNSWER: 60 years
