We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:

(1) d < 1/4 -- It means the possible values of d are .246, .234, .224, .214 & .206
Now when we round these numbers, .246 gives .25, .236 gives .24 etc. So we can't be sure of the value.
(2) h < 5 -- Same condition with same alternatives.

So none is sufficient, hence E. _________________

(1) d < 1/4 -- It means the possible values of d are .246, .234, .224, .214 & .206 Now when we round these numbers, .246 gives .25, .236 gives .24 etc. So we can't be sure of the value. (2) h < 5 -- Same condition with same alternatives.

So none is sufficient, hence E.

We are asked to round to the nearest tenth.... Your reasoning is okay, but the answer would be D.....

If d<1/4 implies h is 4,3,2,1
In that case possible values of d are
d=0.246,0.236,0.226,0.216 and 0.206
the question asks for finding the tenth digit of d
In all these values of d we have, we will get d=0.2
Same reasoning with with h<5.
So answer is D

but for the value of .246, the value of d at the tenths place is .3 because .246 when rounded becomes .25 which when again rounded becomes .3.
Please correct me if i am wrong.

I too had a doubt regarding this and checked a few sites.
But it is not like that. We just have to look at only the next right digit to decide.
If rounding upto tenths is reqd, just look at the hundredth digit etc..

I am not panicking. Nope, Not at all. But I am beginning to wonder what I was thinking when I decided to work full-time and plan my cross-continent relocation...

Over the last week my Facebook wall has been flooded with most positive, almost euphoric emotions: “End of a fantastic school year”, “What a life-changing year it’s been”, “My...
