Answers
Given : number which when divided by 25,45,55 leaves the remainders 12,17,27 respectively.
To Find : the smallest number
Solution:
N = 25A + 12
N = 45B + 17 = 45(B + 1) - 28
N = 55C + 27 = 55(C + 1) - 28
=> N + 28 = 45(B + 1) = 55(C + 1)
Find LCM of 45 & 55
= 495
=> N + 28 = 495K
=> N = 495K - 28
495K - 28 = 25A + 12
=> 495K = 25A + 40
=> 99K = 5A + 8
=> K = 2 & A = 38
N = 495K - 28
= 495 * 2 - 28
= 990 - 28
= 962
962 is the smallest number which when divided by 25,45,55 leaves the remainders 12,17,27 respectively.
962 = 25 * 38 + 12
962 = 45*21 + 17
962 = 55*17 + 27
