Question

What will come in the place of the question mark (?) in the following equation, if "+' and ' are interchanged and 'x' and '÷' are interchanged? 19 + 55 × 5-7 ÷ 3=?

• A. 33
• B. 41
• C. 29
• D. 37

Answer 1

Answer:

C. 29

‘+’ and ‘−’ are interchanged

‘×’ and ‘÷’ are interchanged

Original expression:
$19 + 55 \times 5 - 7 \div 3$

After interchanging:
$19 - 55 \div 5 + 7 \times 3$

Now solve using BODMAS

$(55 \div 5 = 11)$

$(7 \times 3 = 21)$

So,
$19 - 11 + 21 = 29$

Answer = 29
