5 ÷ 10 × 12 + 14 - 7 = 88

1. 10 and 5, - and ×
2. 14 and 7, × and ÷
3. 5 and 7, + and -
4. 5 and 12, + and -

Answer 1

Correct Answer - Option 1 : 10 and 5, - and ×

Given,

5 ÷ 10 × 12 + 14 - 7 = 88

1) 10 and 5, - and × 

= 10 ÷ 5 - 12 + 14 × 7

= 2 - 12 + 98

= 88 = 88

2) 14 and 7, × and ÷ 

= 5 × 10 ÷ 12 + 7 - 14

= 4.16 - 7

= 2.84 ≠ 88

3) 5 and 7, + and - 

= 7 ÷ 10 × 12 - 14 + 5 

= 8.4 - 9

= - 0.6 ≠ 88

4) 5 and 12, + and - 

= 12 ÷ 10 × 5 - 14 + 7

= 6 - 14 + 7

= -1 ≠ 88

Hence, the correct answer is 10 and 5, - and ×.
