let the age of granddauther be x years.
therefore, grandfather's age will be = 10 times of x =6x
From Question, 6x. = x + 54
= 6x - x = 54
= 5x = 54
= x = 54÷5 = 10.8
therefore. grandfather' s present age is = 6x = 10.8 × 6 = 64.8 years and that of granddauter = 10.8 years
therefore, grandfather's age will be = 10 times of x =6x
From Question, 6x. = x + 54
= 6x - x = 54
= 5x = 54
= x = 54÷5 = 10.8
therefore. grandfather' s present age is = 6x = 10.8 × 6 = 64.8 years and that of granddauter = 10.8 years
