Question 34

If 12 # 168 = 14, 13 # 78 = 6 and 1 # 4 = 4, then find the value of 15 # 165 = ?

Solution

Given, 12 # 168 = 14, 13 # 78 = 6 and 1 # 4 = 4

The logic here is

$$\frac{168}{12}=14$$

$$\frac{78}{13}=6$$

$$\frac{4}{1}=4$$

The coded value is the division of second number and first number.

Similarly,

$$\frac{165}{15}=11$$

$$\therefore\ $$15 # 165 = 11

Hence, the correct answer is Option A
