.Out of 25 students, 5 are absent, what percentage of the students are absent?

Answer 1

Answer:

. QR corresponds to BC

. 15 days in hours = 15×24 = 360

360/72 = 5/1

Therefore, ratio = 5:1

. Profit = CP-SP = 1000-800 == Rs. 200

Percentage = 200/800 ×100 = 25%

. No of potatoes for Rs. 96 = 7/42 × 96

= 1/6 ×96 = 16 kg

. 5/25 × 100 = 20%
