Question 14

If 17 + 17 = 2895

18 + 18 = 3245
19 + 19 = 3615
then 23 + 23 = ?

Solution

The pattern followed is that the square of the number is taken and 5 is added at the end.

Eg : $$17^2=289\equiv2895$$

Also, $$18^2=324\equiv3245$$ and $$19^2=361\equiv3615$$

Similarly, $$23^2=529\equiv5295$$

=> Ans - (D)
