A number x is three times another number y. If the sum of both the numbers is 20, then x and y, respectively, are:
Answer & explanation
Correct answer: option 2
x = 3y
If the sum of both the numbers is 20
Now, x + y = 20
= 3y + y = 20
= 4y = 20
= y = 5
The value of x
x + y = 20
= x + 5 = 20
= x = 20 - 5 = 15
So the values of x and y = 15 and 5
