Question 40

If 9#3 = 120, 3#4 = 70 and 2#9 = 110, then Find the value of 5#2 = ?

Solution

Given : 9#3 = 120, 3#4 = 70 and 2#9 = 110

If we replace '#' with '+', and multiply the sum by 10, we get the desired result.

Eg :- $$(9+3)\times10=120$$

and $$(3+4)\times10=70$$ and $$(2+9)\times10=110$$

Similarly, $$(5+2)\times10=70$$
