Question

What will come in the place of "?' in the following equation, if '+' and '-' are interchanged and 'x' and '-' are interchanged? 56 - 33 × 3÷4 + 36 =?

• A. 64
• B. 68
• C. 72
• D. 74

Answer 1

Answer:

A. 64

Interchange the signs as given:

• (+) and (−) are interchanged

• (×) and (÷) are interchanged

Original expression:
$56 - 33 × 3 ÷ 4 + 36$
After interchange:
$56 + 33 ÷ 3 × 4 - 36$
Now solve using BODMAS:

33 ÷ 3 = 11
11 × 4 = 44
56 + 44 - 36 = 100 - 36 = 64
