my solution to teaser 2598

[ahmet cetinbudaklar]

Dear Teasermaster:

In today's teaser I listed all the possible squares and prime numbers as follows:

Squares: 121 , 144 , 225 , 256 , 361 , 441 and 625

Prime numbers: 113 , 131 , 151 , 163 , 211 , 223 , 233 , 241 , 251 , 263 , 311 , 313 , 331 , 353 , 421 , 431 , 433 , 443 b, 461 , 463 , 521 , 523 , 541 , 563 , 613 , 631 , 641 , 643 , 653 and 661.

The number I see at the front and the number seen by the observer from the front add up to 7 for each dice.

The top number I read is from my right to my left and the reverse is true for the observer.Hence the only square number with its reverse being a prime 361 and if I try this as the top face of  three dice , then by trial and error we can get:

152  (reverse reading 251-a prime)

361 (read left to right a square and reverse reading is a pirme)

625 (read left to right is a prime)

Hence we have 2 prime numbers and 2 squares respectively giving us the answer to this etaser as 361 and 625.

Nice and   neat problem.

With my best regards
