1) always zero

2) could be 0-9

if z = 0.132, 100z = 13.21 tenths digit 2, hundreths digit 1

E.

z = 0.xyabc.... We need to find the value of y!!!

1) 100z = xy.abc. Tenths digit = a = 2. Insuff
2) 1000z = xya.bc. Units digit = a = 2. Insuff

Taking it together we do not have any additional info to find value of y.

Hence E.

100*.132 = 13.2.. tenth digit is 2..
1000*.1322 = units digit is 2..

I think here 2 would be the repetitive sequence.. hence the hundredth digit should be 2.

E

cause if you multiply the decimal with 100 its hundredths digit will become the unit digit in new number so .... A in InSuff

B multiply the Decimal with 1000 and its Hundredths digit will become the tens digit of new number so InSuff

both also does not help .....hence E
