Model 1: Find the missing character from the given figure.
(S.S.C. 2002)
Solution:
By observing the given pattern: moving in clockwise direction,
4 x 1 = 4
4 x 2 = 8
8 x 3 = 24
24 x 4 = 96
96 x 5 = 480
480 x 6 = 2880
So, required number = 2880.
Model 2: Find the missing character from the given alternative.
(M.A.T. 2002)
Solution:
Consider
A = 1, B = 2, C = 3, ......., X = 24, Y = 25, Z = 26.
By observing the given figure,
F + P = 6 + 16 = 22
G + N = 7 + 14 = 21
J + E = 10 + 5 = 15
Since K = 11, so value corresponding to missing letter = 27 - 11 = 16.
Hence, missing letter is the 16th letter of the English alphabet i.e. P.
Model 3: Find the missing character from the given pattern.
(IGNOU, 2003)
Solution:
By observing the given pattern,
[latex]\frac{5 * 6 * 4}{10}[/latex] = 12
[latex]\frac{6 * 7 * 5}{10}[/latex] = 21
Now, missing character is [latex]\frac{4 * 8 * 10}{10}[/latex] = 32
Model 4: Find the missing number.
(C.B.I. 2003)
Solution:
By observing the given pattern,
[latex]\frac{13 + 19}{8}[/latex] = 4
[latex]\frac{71 + 9}{8}[/latex] = 10
So, missing character = [latex]\frac{128 + 32}{8}[/latex] = 20
Model 5: Find the missing character from the given figure.
(S.S.C. 2002)
Solution:
From the first figure (56 + 15) - (22 + 8) = 41
From the second figure, (46 + 9) - (10 + 6) = 39
Now, missing number = (34 + 11) - (14 + 6) = 25
Hence, missing number is 25.
