Find the missing number given the following clues The ones d

Find the missing number, given the following clues: The ones digit is 6 when rounded to nearest whole number. The one\'s digit is twice the thousandth\'s digit. The ten\'s digit is twice the tenth\'s digit. The tenth\'s digit is two less than the thousandth\'s digit. The hundredth\'s digit is equal to the square of the tens digit

Solution

Let number be

rs.tuv

From b) we have s is even

When rounded to whole number ones digit becomes 6 so it must be 6 because on rounding ones digit can only change by 1 atmost

And 5 and 7 are ood but s is even

So, s=6

From b)one\'s digit is twice thousandth digit

So, s=2v

Hence, v=3

From c)

r=2t

So r is even

Hence, t can take values:0,1,2,3,4

d) tenth\'s is two less than thousandth digit

t=v-2=3-2=1

t=1,r=2

e)

u=t^2=1

So number is

26.113
