Given below is an equation which has to be solved by following the interchange i.e.,

+ becomes - and - becomes +

×\times becomes ÷\div and ÷\div becomes ×\times

Then what is the value of:

100 ÷ \div 5 + 20 - 10 ×\times 2 = ?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 485.

Given equation: 100 ÷ \div 5 + 20 - 10 ×\times 2 = ?

On interchanging the sign:

100 × 5 - 20 + 10 ÷ 2 = ?

? = 500 - 20 + 5

? = 505 - 20 = 485
