Five set of numbers from 1 to 10 are formed as (1, 2), (3, 4), (5, 6), (7, 8) & (9, 10)
If first set is coded as 5
Second set is coded as 7
Third set is coded as 6
Fourth set is coded as 8
Then code for fifth set is
There are total 5 letters used in the spellings of ONE and TWO. These letters are {O, N, E, T, W} (Repeated letter will not be counted twice)
Similarly for all sets.
First number is 792
Next number is 7*9|9*2= 6318
Next number is 6*3|3*1|1*8= 1838
Similarly for second set
First number is 463
Next number is 4*6|6*3= 2418
Next number is 2*4|4*1|1*8= 848

In first product 1.67 has 3 digits and 2.191 has 4 digits, therefore answer should be written up to 3 digits (minimum number of digits used)
In second product 4.76 has 3 digits and 3.12 has 3 digits too, therefore answer should be written up to 3 digits (minimum number of digits used)
In last product 1.6 has 2 digits only hence 3.9 (rounded off) is the answer.
Every circle intersects other circle in maximum 2 points or minimum 0 point.
Total number of combinations of circle are 10 hence maximum points are 20.
Minimum intersecting points are 0.
Total no. of combinations are 4*3*2*1=24
There are 6 ways for making a pair of B-a, similarly 6 ways are possible for the pair A-c in these ways 2 ways are common hence total no. of rejected ways
=6+6-2=10
Similarly 6-6 ways are possible for the combination of C-b and C-d, in these ways 3-3 ways are affiliated with pair A-c and B-a hence only 3-3 ways are acceptable
A representation for the pair C-b is
C-b A-a B-c D-d (selected)
C-b A-a B-d D-c (selected
C-b A-c B-a D-d (rejected)
C-b A-c B-d D-a (rejected)
C-b A-d B-a D-c (rejected)
C-b A-d B-c D-a (selected)
