Let the quantity of water initially be 3x.

⇒ Milk = 8x

3x  + 3/8x = 1/2 

⇒ 6x + 6 = 8x

⇒ x = 3

⇒ The quantities of milk in the mixture initially = 8x = 24 litres

⇒ The quantities of water in the mixture initially = 3x = 9 litres

∴ The quantities of milk and water respectively in the mixture initially are 24 litres and 9 litres.

Calculation:

Number of engineering students = 34% of 2000 = 0.34 × 2000 = 680

⇒ Number of boys pursuing engineering = 5/8 × 680 = 425

Number of medical students = 13% of 2000 = 0.13 × 2000 = 260

⇒ Number of boys pursuing medical = 7/13 × 260 = 140

Number of commerce students = 28% of 2000 = 0.28 × 2000 = 560

⇒ Number of boys pursuing commerce = 4/7 × 560 = 320

Number of arts students = 25% of 2000 = 0.25 × 2000 = 500

⇒ Number of boys pursuing arts = 2/5 × 500 = 200

Total number of boys in college = 425 + 140 + 320 + 200 = 1085

∴ Required percent = 1085/2000 × 100 = 54.25%

Given:

Concept:

If ratio of A and B is = x ∶ y

∴ A/B = x/y

Calculation:

Number of passing students in 2013 = 1000 × 75% = 750

Number of passing students in 2014 = 1250 × 50% = 625

Number of failed students in 2014 = (1250 ─ 625) = 625

Required ratio = 750 : 625 = 6 ∶ 5

∴ Required ratio is 6 ∶ 5

Solution -The logic follows here is:
The total number of triangles here are 9 as given below
