question is wrong

Question:

Find the greatest number which is such that when 12288, 19139 and 28200 are divided, the remainders are all the same?

Options:
A)

121

B)

122

C)

221

D)

223

Solution:

Ans: (c)

Greatest number means find HCF

12288        19139        28200    

Difference     = (19139 – 12288), (28200 – 19139), (28200 – 12288)

= (6851), (9061), (15912)

= (9061 – 6851), (15912 – 9061)

= 2210, 6851

= 221 × 10, 221 × 31

HCF = 221

Greatest number = 221
