Question

Which two signs should be interchanged in the following equation to make it correct? 3 - 6 × 18 + 4 ÷ 2 = 2

• A. - and ÷
• B. × and -
• C. × and ÷
• D. × and +

Answer 1

Answer:

B. × and -

1) - and ÷ 

Given equation: $3-6\times{18}+4\div{2}=2$

After interchanging the signs, we get:

L.H.S $=3\div{6}\times{18}+4-2$

$=0.5\times{8}+4-2$

= 9 + 4 – 2

= 13 – 2

= 11 ≠ R.H.S

2) × and –

Given equation: 3 - $6\times{18}+4\div{2}=2$

After interchanging the signs, we get:

L.H.S = $3\times{6}-18+4\div{2}$

= 18 – 18 + 2

= 2 = R.H.S

Hence, ‘× and –’ is the correct answer.
