Answer:
Hence, the number of adult dinosaurs = 4
Hence, the number of baby dinosaurs = 132
Step-by-step explanation:
Let the number of adult dinosaurs be x and
the number of baby dinosaurs be y
Now, number of paintings made by each baby dinosaur = 1515
And no. of painting made by each adult dinosaur = 77
Total paintings = 208208
⇒ 77x + 1515y = 208208 .......(1)
Now, baby dinosaurs are 33 times as many as adult dinosaurs
⇒ 33x = y.........(2)
Now, putting this value of y in equation (1)
⇒ 77x + 1515 × 33x = 208208
⇒ 77x + 4995x = 208208
⇒ 50072x = 208208
⇒ x = 4.16
Hence, the number of adult dinosaurs = 4
Now, from equation (2)
y = 33×4
⇒ y = 132
Hence, the number of baby dinosaurs = 132
