In each of the following questions, the two expressions on either side of the sign (=) will have the same value if two terms on wither side or on the same side are interchanged. The correct terms to be interchanged have been given as one of the four options under the expressions. Find the correct option in each case.
`5 +3 xx 6 - 4 div 2 = 4 xx 3 - 10 div 2 + 7`

Options

A. `4,7`
B. `5,7`
C. `6,4`
D. `6,10`

Answer

C

Explanation

Interchanging 6 and 4 on L.H.S (Left hnd side) in the give expressions, we get
`5 + 3 xx 4 - 6 div 2 = 4 xx 3 -10 div 2 + 7`
Using BODMAS RULE, we get
`5 + 3 xx 4 - 3 = 4 xx 2 - 5 + 7`
` or, 5 +12 - 3 = 12 - 5 + 7`
or, `17 - 3 = 19 -5`
or, `14=14` whihc is correct.
