Answer:
Rex's age = x = 32 years (approximately)
Step-by-step explanation:
Let Rex's age be x.
Spike's age = x/6.
Rex's mother's age = 10x.
Rex's father's age = 20x.
Granduncle's age = sum of all the above ones = 1000.
=> x + x/6 + 10x + 20x = 1000
=> (6x + x + 60x + 120x)/6 = 1000
=> 187x = 6000
=> x = 6000/187
=> x = 32 years (approximately) = Rex's age.
