The present age of Sahil’s mother is three times the present age of Sahil. After 5 years their ages will add to 66 years. Find their present ages.

Step-by-step Explanation:

Let the age of Sahil's mother be x and the age of Sahil be y. Then according to question.

• Sahil's mother age = 3(Sahil's age)

➛ x = 3y -----------(1)

And according to second condition,

• Sahil's mother age + 5 + Sahil's age + 5 = 66

➛ x + 5 + y + 5 = 66

➛ x + y + 10 = 66

➛ x + y = 56 ----------(2)

Now substituting x = 3y in equation (2)

➛ 3y + y = 56

➛ 4y = 56

➛ y = 14

Then,

➛ x = 3(14) = 42

Hence:-

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
