Correct Answer: 7 and 14, × and ÷
Solution :
Given:
7 × 14 ÷ 6 + 12 + 6 = 30
Let's check the options –
First option:
7 and 6, × and ÷
Since there are two 6s in the equation, it is not clear which 6 needs to be interchanged. So, this option is incorrect.
Second option:
7 and 14, × and ÷
On interchanging the numbers and symbols, the equation becomes –
14 ÷ 7 × 6 + 12 + 6 = 30
Solving the L.H.S. of the equation –
= 2 × 6 + 12 + 6
= 12 + 12 + 6
= 30
Third option:
7 and 6, ÷ and +
Since there are two 6s in the equation, it is not clear which 6 needs to be interchanged. So, this option is incorrect.
Fourth option:
6 and 14, × and +
Since there are two 6s in the equation, it is not clear which 6 needs to be interchanged. So, this option is incorrect.
So, only the second option satisfies the condition. Hence, the second option is correct.
