If the given interchanges are made in sign and numbers, which one of the four equations would be-correct?
Interchanges - Signs - and x
- Numbers 3 and 6
A. $$6 - 3 \times 2 = 9$$
B. $$6 \times 3 - 4 = 15$$
C. $$3 \times 6 - 4 = 33$$
D. $$3 - 6 \times 8 = 10$$
Choose the most appropriate answer from the options given below:

A. $$6 - 3 \times 2 = 9$$ 

After interchanges 

$$3 \times 6 - 2 = 9$$

This is incorrect as L.H.S = 16

B. $$6 \times 3 - 4 = 15$$

After interchanges

$$3 - 6 \times 4 = 15$$

This is incorrect as L.H.S = - 21 

C. $$3 \times 6 - 4 = 33$$

After interchanges

$$6 - 3 \times 4 = 33$$

This is incorrect as L.H.S = -6

D. $$3 - 6 \times 8 = 10$$

After interchanges

$$6 \times 3 - 8 = 10$$

This correct as L.H.S. = R.H.S. = 10
