Question

Select the correct combination of the mathematical signs that can be filled to balance the following equation:

12__4__2__2__5__3

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

Answer 1

Correct Answer - Option 2 : ÷, ×, +, =, +

1) +, =, ÷, ×, + 

Given expression is 12__4__2__2__5__3

Replacing __ with mathematical signs and applying BODMAS rule, we get :

12 + 4 = 2 ÷ 2 × 5 + 3

L.H.S = 12 + 4 

= 16

R.H.S = 2 ÷ 2 × 5 + 3

= 1 × 5 + 3

= 5 + 3

= 8

L.H.S ≠ R.H.S

2) ÷, ×, +, =, +

Given expression is 12__4__2__2__5__3

Replacing __ with mathematical signs and applying BODMAS rule, we get :

12 ÷ 4 × 2 + 2 = 5 + 3

L.H.S = 12 ÷ 4 × 2 + 2

= 3 × 2 + 2

= 6 + 2

= 8

R.H.S = 5 + 3

= 8

L.H.S = R.H.S

3) ÷, ×, -, =, ×

Given expression is 12__4__2__2__5__3

Replacing __ with mathematical signs and applying BODMAS rule, we get :

12 ÷ 4 × 2 - 2 = 5 × 3

L.H.S = 12 ÷ 4 × 2 - 2

= 3 × 2 - 2

= 6 - 2

= 4

R.H.S = 5 × 3

= 15

L.H.S ≠ R.H.S

4) ÷, ×, =, +, +

Given expression is 12__4__2__2__5__3

Replacing __ with mathematical signs and applying BODMAS rule, we get :

12 ÷ 4 × 2 = 2 + 5 + 3

L.H.S = 12 ÷ 4 × 2

= 3 × 2

= 6

R.H.S = 2 + 5 + 3

= 10

L.H.S ≠ R.H.S

Hence, ÷, ×, +, =, + is the correct answer.
