If NM 2 RRM where N M R are distinct digits Then possible values for R are a 1 b

As the units place digit is repeated so ,so this digit could be: 0,5,1,6.
Now 15^2=225,21^2=441(NM^2=RRM condition satisfied).So, possible values of R=1,2

as in unit place in answer is same
M = 0, 1, 5, 6,
to get answer 3 digit, number is less than 32² (1024)
21² = 441
N = 2, M = 1, R = 4

Possible values of M are 0,1,5,6
So 21^2 = 441
therefore R = 4
also 15^2 = 225
therefore R = 2
ans may be (b). 2

how you are predicting values for m?

the possible r value is 2 only

M=0,1,5,6
to get answer in 3-digit no. should be less than (32)^2(1024)
so (21)^2=441,
hence, N=2, M=1, (R=4)

If (NM)2= RRM where N.M & R are distinct digits. Then possible values for R are

(a) 1 (b) 2 (c) 3 (d) none of these
