∴ 88 does not lies between 27 to 87.
Question : 10
If x, y, z be the digits of a number beginning from the left, the number is
a) xyz
b) x + 10y + 100z
c) 10x + y + 100z
d) 100x + 10y + z
Answer »Answer: (d)
In this problem, the digits of the number from the left are x, y and z respectively.
So, x is at hundreds places, y is at tens place and z is at ones place.
Thus, the required number be
= (100×x) + (10×y) + (1×z)
= (100x + 10y + z)
