Kudos for a correct  solution .

shreyast · Answer

So, we have a=c and b=c ; therefore a =b
100,000 microns = 1,000,000,000 angstroms
Therefore, 1 micron = 10,000 angstroms. (Cancel out 5 zeros from both sides). Option D.

\frac{1,000,000,000}{100,000} =10,000

D

KS15 · Answer

Answer=D

100,000 microns=1,000,000,000 angstroms
Therefore, Angstroms/microns=10,000

OptimusPrepJanielle · Answer

Given that 100,000 microns = 1 decimeter So, 1 micron = (1 * 1)/100,000 = 1/100,000 decimeter Also, 1 decimeter = 1,000,000,000 angstorm So, 1/100,000 decimeter = /1 = 10,000 Hence option (D). -- Optimus Prep's GMAT On Demand course for only $299 covers all verbal and quant. concepts in detail.

In Our School days we use to solve wavelength questions through (for physics lover)

1A--10^(-10)m
1 micron ----106(-6)m
 so if we divide one by another we will get 1 micron ----10^4 angstrom

If 100,000 microns = 1 decimeter, and 1,000,000,000 angstroms = 1 decimeter, how many angstroms equal 1 micron?

A. 0.00001
B. 0.0001
C. 0.001
D. 10,000
E. 100,000

100,000 microns = 1 dec
1,000,000,000 angstroms = 1 dec

stripe of 5 0's in micron/dec line
stripe of 5 0's in the angstrom/dec line

You are left with 4 0's = 10,000

D.

PareshGmat · Answer

Converting the given information in exponent form & re-writing

10^5 microns = 10^9 angstroms

1 micron  = 10^{9-5} = 10000  angstroms

Answer = D

gps5441 · Answer

Micron=Decimeter=Angstroms

1*10ˆ5=1=1*10ˆ9 
or
 1=1*10ˆ9/1*10ˆ5=1*10ˆ9-ˆ5=1*10ˆ4=10000

hasnain3047 · Answer

100,000 microns = 1,000,000,000 angstroms

so 1 micron = 10,000 angstroms

MathRevolution · Answer

1 decimeter = 100,000 microns

1 decimeter = 1,000,000,000 angstroms

=>100,000 microns = 1,000,000,000 angstroms

=> 1 micron = 1,000 angstroms

Answer D

rahulbhusan · Answer

Given, 
1 dm (decimeter) = 10^5 microns - (i)
1 dm = 10^9 angstroms - (ii)
so, from (i) and (ii)
10^5 microns = 10^9 angstroms
=> 1 micron = 10^4 angstroms
option  D  satisfies.

Sure Brunel. Edited the post. Apologies!!

Feynmann01 · Answer

We have :
10^5 m = 10^9 a
Divide both side by 10^5

We get : 1 m = 10^4 a

Hence answer D
