View answer & explanation

Correct answer

Answer: (d)D.

78

Why this answer is correct

The logic follows here, 

Logic: The series follows a pattern where each subsequent number is obtained by adding consecutive multiples of 5 to the previous number.

  • 63 + 5 = 68
  • 68 + 10 = 78
  • 78 + 15 = 93
  • 93 + 20 = 113
  • 113 + 25 = 138

The missing number in the series is 78.

Hence, the correct answer is "Option 4"

9

Why this answer is correct

BODMAS Rule:

:

LetterABCD
Operator÷×+−

 

Given Expression: 36 A 3 C 21 D 12 B 2 = ?

After substituting the letters and following BODMAS rule 

= 36 ÷ 3 + 21 − 12 × 2

= 12 + 21 − 12 × 2

= 12 + 21 − 24

= 31− 24 

= 9

Hence, the correct answer is "option 3"
