Question 40

If 210 = 6, 1416 = 15 and 416 = 10, then find the value of 168 = ?

Solution

Given : 2*10 = 6, 14*16 = 15 and 4*16 = 10

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

Eg :- $$\frac{2+10}{2}=6$$

and $$\frac{14+16}{2}=15$$ and $$\frac{4+16}{2}=10$$

Similarly, $$\frac{16+8}{2}=12$$
