Answer 1

Answer:

B. 7, 14

Solution: The pattern followed here is: Given: × and ÷ , 3 and 11 I. 2 + 6 × 11 ÷ 8 - 3 After interchanging the sign and number we get the equation is; × and ÷ , 3 and 11 ⇒ 2 + 6 ÷ 3 × 8 - 11 ⇒ 2 + 2 × 8 - 11 ⇒ 2 + 16 - 11 ⇒ 18 - 11 ⇒ 7 II. 7 ÷ 11 - 3 + 16 × 4 After interchanging the sign and number we get the equation is; × and ÷ , 3 and 11 ⇒ 7 × 3 - 11 + 16 ÷ 4 ⇒ 7 × 3 - 11 + 4 ⇒ 21 - 11 + 4 ⇒ 25 - 11 ⇒ 14 Hence, the correct answer is "7, 14".
