Rex is six times older than its sibling Spike. Rex's mother dino is ten times older than Rex. Rex's father dino is twice as old as Rex's mother. The sum of all the ages of the members of dino's family adds up to granduncle dino's age. The granduncle dino had just turned thousand years old the day the meteors hit the planet. How old was Rex when it became a fossil into the nearest Whole number?​

30 years

Step-by-step explanation:

Let :

Spike's age = x

Rex age = 6x

Rex mother = 10 * 6x = 60x

Rex father = 2 * 60x = 120x

x + 6x + 60x + 120x = 1000

187x = 1000

x = 1000/ 187

x = 5.34

Hence, Spike's age, x = 5 years

Rex age = 5 * 6 = 30 years
