Since 9 questions is 60% of the exam, you must find 100%. You could find the value of 10% by dividing 60 by 6. You do the same to 9, divide by 6 to get 1.5. Now that you have the value of 10% you can multiply 10% by 10 to get 100. You also do the same to 1.5. Your answer should be 15, if not check your work again.

Answer:
1.47 years
Step-by-step explanation:
Given that,
The height of male elephant is given by the formula,
![h=62.5\sqrt[3]{t} +75.8](https://tex.z-dn.net/?f=h%3D62.5%5Csqrt%5B3%5D%7Bt%7D%20%2B75.8)
If h = 275 cm, we need to find the age of the elephant.
Put h = 275 cm in the above formula,
![275=62.5\sqrt[3]{t} +75.8\\\\275-75.8=62.5\sqrt[3]{t}\\\\199.2=62.5\sqrt[3]{t}\\\\t=1.47\ years](https://tex.z-dn.net/?f=275%3D62.5%5Csqrt%5B3%5D%7Bt%7D%20%2B75.8%5C%5C%5C%5C275-75.8%3D62.5%5Csqrt%5B3%5D%7Bt%7D%5C%5C%5C%5C199.2%3D62.5%5Csqrt%5B3%5D%7Bt%7D%5C%5C%5C%5Ct%3D1.47%5C%20years)
So, the required time be 1.47 years.
