Test: Inserting the Missing Character - UPSC MCQ

In the first row, F + I = 6 + 9 = 15 = O.
In the second row, A + J = 1 + 10 = 11 = K.
So, in the third row, missing letter = E + M = 5 + 13 = 18 = R.
Hence, the answer is (b).

In the third column, 16 × ( 32 ÷ 4) = 128
Let the missing number be x. Then, in the second column, we have :
14 × ( 24 ÷ x) = 112 ⟺ 24 ÷ x = 8 ⟺ x = 3.
Hence, the answer is (b).

In each row, out of the letters A, B and C, each of these must appear once.
Also, in each column, the product of the first and third numbers is equal to the second number.
So, the missing number will be (2 × 4) i.e 8 and the missing number letter will be C.
Thus the answer is 8C.
Hence, the answer is (a).

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.
So, the missing letter is the 16th letter of the English alphabet, which is P. Hence, the answer is (b).

Missing number = (7 × 10) – (4 × 6) = 46.
Hence, the answer is (b).

So, missing number = (17 – 13)² + (51 – 48)² = 4² + 3² = 25.
Hence, the answer is (b)

4 × 1 = 4;  4 × 2 = 8; 8 × 3 = 24; 24 × 4 = 96; 96 × 5 = 480
So, required number = (480 × 6) = 2880.
Hence the answer is (c)

So, missing number = (34 + 11) – (14 + 6) = 25.
Hence, the answer is (b).

In the second column, ( 5 × 8) – 2 = 48.
So, missing number = ( 6 × 9) – 3 = ( 54 – 3) = 51.
Hence, the answer is (c).
