Question 40

If 4!4 = 4, 14!2 = 8 and 10!18 = 14, then find the value of 2!6 = ?

Solution

Given : 4!4 = 4, 14!2 = 8 and 10!18 = 14

If we replace '!' with '+', and divide the sum by 2, we get the desired result.

Eg :- $$\frac{4+4}{2}=4$$

and $$\frac{14+2}{2}=8$$ and $$\frac{10+18}{2}=14$$

Similarly, $$\frac{2+6}{2}=4$$

=> Ans - (A)
