Question

110 and 128
as the remainder is 2 for both ( therefore ) NOS 108 and 126 TO find greatest no which divides them we will find HCF.
[
begin{array}{l|lll}
2 & 108 & , & 126
3 & 54 & , & 63
3 & 18 & , & 21
& 6 & , & 7
end{array}
]
( therefore H C F=2 times 3^{2} )
[
=18
]

# 15. What is the greatest number which will divide 110 and 128 leaving a remainder 2 in each case? (1) 8 (2) 18 (3) 28 (4) 38
