Question 29

If 8 * 9 # 3 = 51 and 12 * 6 # 4 = 72, then 13 * 11 # 6 = ?

Solution

Given = 8 * 9 # 3 = 51 and 12 * 6 # 4 = 72

If we replace '*' by '+' and '#' by 'x' and perform the add operation first, we get the desired result

Eg :- $$(8+9)\times3=17\times3=51$$

and $$(12+6)\times4=18\times4=72$$

Similarly, $$(13+11)\times6=24\times6=144$$
