Question

Select the correct combination of mathematical signs to replace 'Y' sequentially and balance the following equation.

18 Y 2 Y 3 Y 3 Y 9

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

Answer 1

Correct Answer - Option 4 : ÷, ×, =, × 

1) ÷, ×, =, -

Given expression: 18 Y 2 Y 3 Y 3 Y 9

After replacing Y’s, we get:

18 ÷ 2 × 3 = 3 – 9

=> 9 × 3 = -6

=> 27 ≠ -6

2) ×, =, -, ÷

Given expression: 18 Y 2 Y 3 Y 3 Y 9

After replacing Y’s, we get:

18 × 2 = 3 – 3 ÷ 9

=> 36 = 3 – 0.34

=> 36 ≠ 2.67

3) ×, ÷, +, =

Given expression: 18 Y 2 Y 3 Y 3 Y 9

After replacing Y’s, we get:

18 × 2 ÷ 3 + 3 = 9

=> 12 + 3 = 9

=> 15 ≠ 9

4) ÷, ×, =, × 

Given expression: 18 Y 2 Y 3 Y 3 Y 9

After replacing Y’s, we get:

18 ÷ 2 × 3 = 3 × 9

=> 9 × 3 = 27

=> 27 = 27

Hence, ‘÷, ×, =, × ’ is the correct answer.
