1. A man sold two cows for Rs 210. If he made a 10% loss on one cow and 10%

profit on the other

cow, and overall made a profit of 5%, how much was each cow worth initially?

ans:

let the original price be x and y ;

x+y=100(210)/105 => x+y=100*210/105

//5% profit

90/100(x)+110/100(y)=210=> .9x+1.1y=210

solve above equations for x and y

The Novice hockey tournaments are on for beginners. Just three teams are in the

league, and each

plays the other two teams just once. Only part of the information appears in the

result chart, which is

given below.

T e am Games Won Lost T i ed G o a l sFor G o a l s against

A 2 1 0

B 2 1 1 2

C 2

The scoring pattern in the tournament is as follows:

Two points are awarded to the winning team. In case of a tie, both teams are

awarded one point, so

the total points in the standings should always equal the total number of games

played ( since each

game played is counted as one for each of the two participating teams). Of

course, total goals scored

for and goals scored against must be the same, since every goal scored for one

team is scored

against another.

The games are played in the following order: Game 1: A Vs B; Game 2: A Vs C;

Game B Vs C

Can you determine the score of each of the above games ?

Ans: A B 0 1

A C 0 0
