Question

find the sums for me

Answer 1

4.a)15% of 250=15÷100×250=37.5
b)1% of 1 hour=1% of 60mins=1÷100×60
=0.6
c)2% of Rs.2500=2÷100×2500
=Rs.50
d)75% of 1kg=75% of 1000gms=75÷100×1000
=750gms

5.a) let the required no.be 'x'
Then,5% of X=600
=>X=600÷5
=120

b) let the required no.be 'x'
Then,12% of X=Rs.1080
=>X=Rs.1080÷12
=Rs.90

c) let the required no.be 'x'
Then,40% of X=500kms
=>X=(500×1000)kms÷40
=500000ms÷40
=12500ms
=12.5kms

d) let the required no.be 'x'
Then,70% of X=14mins
=>X=(14×60)secs÷70
=840secs÷70
=12 secs
.
e) let the required no.be 'x'
Then,8% of X=40litres
=>X =40 litres÷8
=5 litres
