Question

Select the correct combination of mathematical signs that can sequentially replace the * signs from left to right to balance the following equation.

32 * 2 * 60 * 30 * 15 * 51

1. ×, -, +, ÷, = 
2. ×, ÷, +, - , =  
3. ×, +, ÷, -, =  
4. -, ÷, +, ×, =  

Answer 1

Correct Answer - Option 3 : ×, +, ÷, -, =  

Given: 32 * 2 * 60 * 30 * 15 * 51

1. ×, -, +, ÷, = 

32 × 2 - 60 + 30 ÷ 15 = 51

32 × 2 - 60 + 2

64 - 60 + 2

66 - 60 = 6 ≠ 51

2. ×, ÷, +, - , =  

32 × 2 ÷ 60 + 30 - 15 = 51

32 × 1/30 + 30 - 15

1.67 + 30 - 15

31.67 - 15 = 16.67 ≠ 51

3. ×, +, ÷, -, =  

32 × 2 + 60 ÷ 30 - 15 = 51

32 × 2 + 2 - 15

64 + 2 - 15 

66 - 15 = 51 = RHS

Hence, ×, +, ÷, -, = is correct..
