Two digit no possibility whose sum is 12 = 39,48,57,66,75,84,93 See the difference of above no with 54 1.39-54=-15 2.48-54=-6 3.57-54=3 4.66-54=12 5.75-54=21 6.84-54=30 7.93-54=39 The last no 7 mentioned shows 93 is the ans because if you reverse it 39 will come it 54 less than 93. And=93

The ninth term of an arithmetic progression is 54 and the sum of the 12 terms 438 find the first term and the common difference?
t(n) = a + 8*d = 54 .. .. .. .. .. .. .. (A) s(12) = 12*a + 66*d = 438 .. .. .. .. (B) 12*(A) - (B) => 12*A + 96*d -12*A - 66*D = 648 - 438 => 30*d = 210 = d = 7 Then substituting this value in (A) gives a + 54 = 54 => a = -2 So the first term is -2 and the common difference is 7.
