Question 30

Some equations have been solved on the basis of a certain operation. Find the correct answer for the unsolved equation on that basis. If 73 * 17 = 45 and 68 * 40 = 54. then 83 * 15 = ?

Solution

Both the numbers are added and the sum is divided by 2

Eg : $$\frac{73+17}{2}=\frac{90}{2}=45$$

and $$\frac{68+40}{2}=\frac{108}{2}=54$$

Similarly, $$\frac{83+15}{2}=\frac{98}{2}=49$$

=> Ans - (A)
