This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300
In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2

Answer:
The figures are not similar
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
Verify
BC/JI=AB/FJ=ED/GH
substitute the given values
5.1/3.6=2.8/2.1=3.7/2.7
1.417=1.333=1.370 ------> is not true
therefore
The figures are not similar
