How about: 3*29 = 87
61 + 73 + 71 + 80 + 87 + 90 + 90 + 90 + 87 + 83 + 73 + 63 = 948 / 12 = 79 The average of the numbers is therefore 79.
For this set of numbers, 45 87 61 73 55 78 69 80: σ=14.0204
hcf(87, 102) = 3. factorization method: 87 = 3 x 29 102 = 2 x 3 x 17 hcf = 3
GCF(58, 29, 87) = 29.
(87/61)x100 = 8700/61 = 142.623%
87
61
61/70 x 100 = 87%
