Method:
A) 1/25
B) 1/50
C) 7/250
D) 4/25
E) 7/200
We can eliminate two options just by comparing fractions and the options are A and E because 1/25>1/50 and 7/200>7/250.
Options left B,C, and D.
I took the LCM of the three fractions as 500 and the fractions are:
B) 10/500
C) 14/500
D) 80/500
B <C<D
This is the method I followed to solve this question. What are some quick methods to solve fraction questions?

I opt for B
Time taken: 1:42 should be maximum 1:20
Denominator must be greater
I eliminated A,D straight away
other option
B<C<E
1/50<7/250<7/100
Time taken: 1:42 should be maximum 1:20
Denominator must be greater
I eliminated A,D straight away
other option
B<C<E
