The above question is about BODMAS or PEMDAS. Before solve this question you have understand about BODMAS and PEMDAS. Also study about what is difference between BODMAS, BEDMAS, BIDMAS, PEDMAS and PEMDAS?
We should also understand about it that when the percentage(%) involve in BODMAS. How we solve it? Where we solved the percentage(%) (which order) in BODMAS.
There is also a symbol "e" in this question. We should also learn about "e". What is "e" ? Why "e" is important in math.
In such kind questions you have to covert e and 100% change into numbers. You have to know that e = 2.72 approximate
and 100% = 100/100 = 1. Therefore
2e × 100%
= 2(2.72) × 1
= 5.44 × 1
