Question

The difference of two numbers, a and b, is 21. The difference of 5 times a and two times b is 18. What are the values of a and b?

Answer 1

This one is tough. I tend to solve this by only logic sooo. This might take a while

Answer 2

a = 14 b = 35

Answer 3

14 * 5 = 70 and 35 * 2 = 70.

Answer 4

35-14 = 21, so it follows all guidelines.

Answer 5

As per question
| a-b|=21. (as difference is given a and
b are not we not know who is greater)
Again
5a-2b=18
Solve the two equations
You will get the answer.
