Why is the answer C ??

the number when rounded to neared thousand is .455
means the number can be 0.4549 or 0.4551
i.e

0.4545
0.4546
0.4547
0.4548
0.4549
0.4550
0.4551
0.4552
0.4553
0.4554

in all the cases teh number rounded to hundred will be 0.46 only rite..

Correction -
0.4545 = .45 when rounded to hundreths.
0.4546 = .45 when rounded to hundreths.
0.4547 = .45 when rounded to hundreths.
0.4548 = .45 when rounded to hundreths.
0.4549 = .45 when rounded to hundreths.
0.4550 = .46 when rounded to hundreths.
0.4551 = .46 when rounded to hundreths.
0.4552 = .46 when rounded to hundreths.
0.4553 = .46 when rounded to hundreths.
0.4554 = .46 when rounded to hundreths.
So we need both the stmts. Hope it helps.

Yeah i see that 0.4545 becomes 0.45 when rounded to hundredths.. but why ?/

0.4545 first becomes 0.455 and then becomes 0.46...

when rounding to hundredths, dont you round first to thousands as it is availalble and then round it to hundredths.. or you only consider the thousands digit when rounding to hundredths.. ?

From statement 1, the answer could either be 0.4551 or 0.4549 (i.e. thousandth no. is either 4 or 5)

taken together with statement 2, you know the thousandth no. is 5 so when you round 0.4551 to the hundreth no. it become 0.46

Neochronic,

you can only round once, and not recursively as you pointed out. Otherwise the result of 0.4545 will be 0.5 and not 0.455. In this case (C) is the right answer since (A) leaves you to choose between 4 or 5 for the thousandths, and (B) narrows that down to only 5.
