II. 12 + 8 ×\times 12 ÷ \div 16 - 7 = 19

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Only II.

I. 27 ÷\div 3 - 18 ×\times 3 + 9 = 24

By interchanging the given two signs (+ and ÷\div),

27 + 3 - 18 ×\times 3 ÷\div 9 = 24

27 + 3 - 6 = 24

30 - 6 = 24

24 = 24 (Correct)

II. 12 + 8 ×\times 12 ÷ \div 16 - 7 = 19

By interchanging the given two signs (+ and ÷\div),

12 ÷\div 8 ×\times 12 + 16 - 7 = 19

8 + 16 - 7 = 19

24 - 7 = 19

17 = 19 (Incorrect)
