Question

For all values of $a$, let $\prec a\succ$ be defined as $\prec a\succ =4a-4$ .Which of the following equals $\prec 6\succ -\prec 5\succ$=?

• A. $\prec 2\succ$
• B. $\prec 3\succ$
• C. $\prec 4\succ$
• D. $\prec 5\succ$
• E. $\prec 6\succ$

Answer 1

The correct option is A $\prec 2\succ$

Given $<a>=4a-4$.

$<6>=24-4=20$.

$<5>=20-4=16$. Now $<6>-<5>=20-16=4$.

$<2>=8-4=4=<6>-<5>$.

option $A$ is correct.
