Question

What percentage of the following
(1) 36 minutes of 2 hours
(2) 250 gm of 4 kg
(3) 800 m of 40 km
(4) 325 paise of ₹16.25

Answer 1

1). 1 Hour = 60 min.
Therefore 2 Hours = 120Mins.
36 minutes of 2 hours = 36 minutes of 120 minutes.
That is 36/120 = 0.3
In % = .0.3 × 100 = 30%.
2). 1Kg = 1000 gm
Therefore 4 Kg = 4000grams.
250 gm of 4kg = 250gm of 4000 gm.
That is 250/4000 = 0.0625.
in % = 0.0625× 100 = 6.25%.
3).1 km = 1000 m.
40 km = 40000m.
therefore 800m of 40 km = 800m of 40000m
that is 800/40000 = 0.02
In % = 0.02 × 100 = 2%.
4).1 rupee = 100paise
16.25 rupee = 16×100+25 = 1625 paise.
325 paise of 16.25 rupee= 325 paise of 1625 paise.
That is 325/1625 = 0.2
In %= 0.2 × 100 = 20%.
