Question

10. At present Maria is 8 years older than his younger brother. After 4 years Maria's
age will be double the age of his brother. Let's find their present age.​

Answer 1

Answer:

Let age of her brother presently = X

Then Maria's age = X + 8

(X+4) * 2 = X + 8 + 4

2X + 8 = X + 12

2X - X = 12 - 8

X = 4

Maria's brother present age = 4 years.

Maria's present age = X + 8 = 12 years.

Answer 2

Answer:

Maria's brother present age is 6 years

Step-by-step explanation:

Maria present age 8+4=12

Maria's brother age- 2x=12, x=12/2 which is 6 years

hope it is correct...
