The problem requires finding the remainder r when dividing a by b using the formula a=bq+r, where q is the quotient and r<b.
For a=112,b=7:
112÷7=16 with no remainder
112=7×16+0
Therefore r=0, which matches with (IV)
For a=118,b=9:
9×13=117
118−117=1
118=9×13+1
Therefore r=1, which matches with (I)
For a=119,b=6:
6×19=114
119−114=5
119=6×19+5
Therefore r=5, which matches with (III)
For a=115,b=8:
8×14=112
115−112=3
115=8×14+3
Therefore r=3, which matches with (II)
Final matching:
| List-I | Remainder | List-II |
|---|---|---|
| (A) a=112,b=7 | r=0 | (IV) |
| (B) a=118,b=9 | r=1 | (I) |
| (C) a=119,b=6 | r=5 | (III) |
| (D) a=115,b=8 | r=3 | (II) |
The correct answer is: (A) - (IV), (B) - (I), (C) - (III), (D) - (II)
