1. 66
2. 68
3. 64
4. 65

Answer 1

Correct Answer - Option 2 : 68

Given:

In an examination of 180 marks of a subject, 75% marks are allocated for theory and the rest for project work.

Veena scored 60% in theory.

Calculations:

Total marks needed = 62% of 180

⇒ (62/100) × 180 = 111.6

Total theory marks = 75% of 180 = 135

Total practice marks = 25% of 180 = 45

Marks he got in theory = 60% of 135 = 81

Required extra marks to get 62% = 111.6 - 81 = 30.6

Now, 30.6 as percentage of 45 marks 

⇒ (30.6/45)100 = 68%

∴ The correct choice is option 2.
