Correct answer

Answer: (d)D.

A A C C R R

Why this answer is correct

Given : C _ R C _ R _ A R _ A _ C A _    

By checking options :

  1. R A C A C A → C R R C A R C A R A A C C A A → (It doesn't Follows the pattern)
  2. R A C A A C → C R R C A R C A R A A R C A C → (It doesn't Follows the pattern)
  3. A C R A C R → C A R C C R R A R A A C C A R → (It doesn't Follows the pattern)
  4. A A C C R R → C A R C A R C A R C A R C A R → (It follows the pattern of : CAR - CAR - CAR - CAR - CAR)

⇒Option - (4) gives the pattern of "C A R C A R C A R C A R C A R"

Hence, "A A C C R R" is the correct answer.

View answer & explanation

Correct answer

Answer: (b)B.

80

Why this answer is correct

Here, we use the BODMAS table given below:

Given:

⇒ 3 - 21 + 153 × 17 ÷ 26

As per the given data:

SymbolMeans
+Subtraction
-Multiplication
÷Addition
×Division

After changing the sign as per the table:

⇒ 3 × 21 - 153 ÷ 17 + 26

Apply BODMAS rule:

⇒ 3 × 21 - 9 + 26

⇒ 63 - 9 + 26

⇒ 89 - 9 = 80

Here, the value of the expression is '80'.

Hence, the correct answer is "Option (2)".
