Answer:
Step-by-step explanation:
chocolate donuta= 35% of 40
=
=
=14
chocolate donuts=14
a.donuts that are not chocolates=40-14
=26
b.donuts with sprikles=24
percent of donjts with sprikles=24/40 *100%
=(2400/40)%
=60%
c.donuts that have cream filling out of donut that have sprikles=8
percent of donuts which have sprikles with cream filling=8/24*100%
=(800/24)%
=33.33%
7.final cost=35% of $124.50
=35/100 *$124.50
=$4357.5/100
=$43.575
8.48% 0f 500
=48/100 *500
=48*5
=240
9.let the number be x
15=60% 0f number
15=60/100 *x
15/x=60/100
do cross multiplication
x*60=15*100
x=1500/60
x=25
therefore the number is 25.
10.let the percent be y%
90=y% of 60
90=y/100 *60
90*100=60y
9000/60=y
y=150 %
therefore 150% 0f 60 is 90
As per the problem,
The larger pump takes 40 minutes to fill the pool.
The smaller one takes 60 minutes.
When both the pumps are working , let the time taken be x minutes , then we can write
Hence, when both the pumps works together, Time taken =24 minutes.
