Question

The sum of three numbers is 81. The first number is 6 more than the second. The third number is 3 times the second. What are the numbers?

Answer 1

Let the second no. be x.
First no. = x+6
Third no. = 3x
Sum= 81

Therefore,
x + x + 6 + 3x = 81
=> 5x + 6 = 81
=> 5x = 81-6
=> x = 75/5
=> x = 15

Answer:
So, the first no. is (15 + 6) 21
The second no. is 15
The third no. is (3*15) 45
