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
