Question 40

If 6@16 = 11, 2@14 = 8 and 8@8 = 8, then ﬁnd the value of 10@18 = ?

Solution

Given : 6@16 = 11, 2@14 = 8 and 8@8 = 8

If we replace '@' with '+', and divide the sumby 2, we get the desired result.

Eg :- $$\frac{6+16}{2}=11$$

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

Similarly, $$\frac{10+18}{2}=14$$
