Let x be the total number of bullets,x/3 will be each share...after each shooting 4 bullets..x/3 -4 will be there with each one..so suming them.....x-12 = x/3x = 18;

It means we have to add 2 letters to the LHS let us take 'TW' and 1 letter to RHS let it be 'N' therefore both will be equal by name

1/3 rd of the contents of a container evaporated on the 1st day. 3/4th of the remaining contents of the container evaporated on the day2. What part of the contents of the container is left at the end of the day2?
Let the original content be Xon first day, X/3 evaporates leaving 2X/3.on second day , 3/4 of 2X/3 evaporates which will leave 1/4 of 2X/3 = X/6 remains.
Bala

Let the content be X.1/3 of the content evaporated. 1/3 (X). The remaining content is X-1/3 (X)=2/3 (X).3/4 of the remaing content evaporated. 3/4(2/3 (X))=1/2(X).So the remainig content is 50%.

Let the height of the hill be dthen time taken to climb the hill = d/4 miles per hourtime taken to come down the hill=d/6 miles per hourTotal time=6hrshence d/4+d/6=6d=48
deepali
- Nov 2nd, 2006
total time taken is 6 hr.Speed 4 miles/hr & 6 miles/hrso avg speed is (2*4*6)/(4+6)=4.8now speed=dist/time so dist=speed * timedist= 4.8 *6=28.8dist on one side=28.8/2=14.4 miles

Can u find the numbers such that sum of every 2 and sum of all 4 may be perfect squares.
praveenscience
- Mar 12th, 2011
The four numbers are:
A. 10430
B. 3970
C. 2114
D. 386
Explanation:
A+B = 14400 = 1202
A+C = 12544 = 1122
A+D = 10816 = 1042
B+C = 6084 = 782
B+D = 4356 = 662
C+D = 2500 = 502
A+B+C+D = 16900 = 1302
Hope this is correct! :)

The formula for area of rectangle is breath*length. It is given that l/b=7/5 From that l=7/5*bLength decreases by 5 and breath increases by 2.so now the new area will be A=(l-5)*(b+2)sub the value of...
