1.
Profit from selling price = 25% of 1000 = 250
Profit from cost price = 1000 - 1000/1.25 = 200

So Profit diff = 250 - 200 = 50.

2.
Content of salt in 4lt sol. = 15% * 4000 = 600gm
Content of salt felt = 15% * 1500 = 225gm
Total salt content left = 600 - 225 = 375gm

3.
Area bull can gaze = (1/4) * (22/7) * 7 * 7 = 38.5

4.
Let total work be x
work done by A = x/2
work done by B = x/20
work left = x - (x/2) - (x/20) = 9*x/20
A can complete x work in 15 days
=> A can complete left work = (15/x) * (9*x/20) = 6.75 days

1.
profit for A= 1000*25/100=250 (as A get profit on sell porice)
and profit of B=(1000-1000*100/125)=200 (as B get profit on cost price)
so profit difference=250-200=50

2.
in 4 ltr mixture salt is=4*15/100=0.6 ltr
and in 1.5ltr mixture salt is=1.5*15/100=0.225 ltr
so now salt is =0.6-0.225=0.375 ltr

3.
as bull is tied on a corner so it can fraze only 1/4th of rope's circular area
so bull can graze=(1/4)*(22/7)*(7^2)=22*7/4=38.5 square cm

4.
total work=1
now A did=1/2
and B did=1/20
so work left=(1-1/2-1/20)=9/20
A can do work in 15 days
so in 1 day A can do 1/15th of the work
so 9/20th wok a can do in more ((9/20)/(1/15) or (9*15/20) or 6.75 days
