Sum of the ages of two brothers is 36 years. If the difference
between their ages is 10. Find their ages
Answers
Answer:
The sum of the ages of A and B is 36 years
The sum of the ages of A and B is 36 yearsLet the ages of A be x and B be y
The sum of the ages of A and B is 36 yearsLet the ages of A be x and B be yx + y = 36
The sum of the ages of A and B is 36 yearsLet the ages of A be x and B be yx + y = 36x = 36 - y (Equation 1)
The difference between their ages is 10.
x - y = 10
x = 10 + y (Equation 2)
Substituting the value of x from Eq.1 to Eq.2
Substituting the value of x from Eq.1 to Eq.236 - y = 10 + y
+ y-y - y = 10 - 36
- 36-2y = -26
y = 26/2
/2y = 13
Substituting the derived value of y in Eq..1
Substituting the derived value of y in Eq..1x = 36 - y
Substituting the derived value of y in Eq..1x = 36 - yx = 36 - 13
x = 23
The age of A is 23 years and the age of B is 13 years.
Answer:
x=23 y=13
Step-by-step explanation:
let x and y be the age of two brothers
A/q
x+y=36----------1
x-y=10-------------2
On adding 1st and 2nd,we get
2x=46
x=23
y=36-23
y=13
