According to questions, provided there is no carrying over in the given addition using letter codes.R = 3 ...(1) S + M = 7 ...(2) S + R + R = 8 ...(3) T + S + T = 4 ...(4) U + T + S = 9 ...(5) From equation (1) & (3) S = 2 From equation (4), T = 1 From equation (5), U + 1 + 2 = (9),U=6 From equation (2), 2 + N =7, N = 5 So TURNS → 16 352
