If `a Delta c = (ab)/(c )`, which of the following equals 5 ?

A

`4 Delta 3 Delta 2`

B

`5 Delta 2 Delta 5`

C

`6 Delta 4 Delta 2`

D

`10 Delta 2 Delta 4`

Text Solution

Verified by Experts

The correct Answer is:
D
Go down the answer choices and try multiplying the first two numbers and divifing by the third until you find the choice that yield 5.
The answer is (D) because `(10xx2)/(4)=5`.
