Hens=50
Goats=45
Camels=8
Some keepers=x,,......(it means 2x in equation, because a man has two feet)


# of tests=2*50+45*4+8*4+2x+312 ( yaha end me 312 kaha we arahe hen, ye samj nahi arahi, baki problem easy he?

# of heads=50+45+4=103+x.
Total number of heads = 50+45+8+x = 103 + x
Now, (2x+312) = (103+x)+224
=> x = 15
Hens-- 50*2 feet =100
Goats-- 45*4 =180
Camels-- 8*4=32

If you count 100+180+32= 312 and this is the actual number of feet
so they add

2*50+45*4+8*4+2x+312

here 2x equation because men have 2 feet so use 2x in equation

Hope you understand

TV duration from 7 to 8 = 1 hour = 60 min

1 min = 60 sec

30 sec X 20 = 600 sec

600 sec = 600/60 = 10 min

Commercials time in minutes = 10

Commercial time as fraction of hour= 10/60 or 1/6 = 0.1666

Commercial time as percentage = 0.1666 X 100 = 16.67%

Commercial time to nearest percent = 17%

Hope this helps

Please solve this one, its answer is 64, but when I am doing it, I get 118

if x=1, y=3, z=4 then evaluate x^2+y^2+z^2-3yz^2

118 is right. Then must be wrong in the book.

Train in 1 hour = 60/1.5 = 40

Plane Speed in 1 hour or 60 min = 80

Plane speed in 20 min= 80/60 * 20 = 26.67

To nearest km = 27
