Question

find two number such that one is 3 times the other and their difference is 134

Answer 1

Let the first number be a

Second number = 3a

According to question

3a - a = 134

=> 2a = 134

=> a = 67

First number = 67

Second number = 201

Answer 2

let the numbers be x ,y

x=3y
x-y=134
 
substitute the value of x in equation 2
3y-y=134
2y=134
y=67

x=3y
x=3 x 67
x=201
