Question 55

# I. 65 11 12 II. 15 3 11What is the sum of the resultants of the two rows ?

Solution

For the first row, as per given rule no. 4

65 + 121 = 186 now we have
186 12 so by rule no. 1 we get
186 + 12 =198

For the second row 15 3 11
By rule no. 4 we have
15+9 = 24
24 11 Now by rule no. 2 we have
24*11 = 264
Thus the sum of two rows is 264 + 198 = 462
