Question 40

If 19 (36) 13 and 37 (81) 28, then what is the value of 'A' in 43 (A) 38?

Solution

The pattern is that the number in the middle is obtained by taking square of the difference of the numbers on each sides.

Eg : $$(19-13)^2=6^2=36$$

and $$(37-28)^2=9^2=81$$

Similarly, $$A=(43-38)^2=5^2=25$$

=> Ans - (B)
