Correct answer

Answer: (d)D.

2

Why this answer is correct

Given

40% of 820 + 60% of 390 – 511 = 49 + ?

Concept Used 

Follow the BODMAS rule according to the table given below:

Calculation 

40% of 820 + 60% of 390 – 511 = 49 + ?

⇒ 4 × 82 + 6 × 39 - 511 - 49 = ? 

⇒ ? = 328 + 234 - 560 

⇒ ? = 2 

∴ The required answer is 2

 

Alternative method:

We can also solve it by fraction method

As we know fraction value of 40% = 2/5

And, 60% = 3/5

40% of 820 + 60% of 390 – 511 = 49 + ?

⇒ 2/5 × 820 + 3/5 × 390 – 511 – 49 = ?

⇒ ? = 328 + 234 - 560 

⇒ ? = 2 

∴ The required answer is 2
