Trick – 1

• In a game of billiards, A can give B ${{x}_{1}}$, points in x and A can give C ${{y}_{1}}$ in y. In a game of z, C can give B

$\left( \frac{y{{x}_{1}}-x{{y}_{1}}}{x\left( y-{{y}_{1}} \right)} \right)z$ points.

Trick – 2

• In a game of ’x’ points, A can give B ${{x}_{1}}$ points and C ${{x}_{2}}$ points (${{x}_{2}}$>${{x}_{1}}$), then B can give C

C $\left[ x\left( \frac{{{x}_{2}}-{{x}_{1}}}{x-{{x}_{1}}} \right) \right]po\operatorname{int}s$

Trick – 3

• A beats B by ${{y}_{1}}$ metres and C by ${{y}_{2}}$ metres in a race of ${{x}_{1}}$ metres. In a race of ${{x}_{2}}$ metres C beats B by

$\left( \frac{{{y}_{1}}-{{y}_{2}}}{{{x}_{1}}-{{y}_{2}}} \right)\times {{x}_{2}}$  metres

Trick – 4

• In a km race A beats B by X metres or t seconds. Then the time taken by A to complete the race is given by

$\frac{t}{x}(1000-x)seconds$

Trick – 5

• A can run a km rate in x min and B in y min(y>x). The distance by which A can beat B is given by

$\left[ 1000\left( 1-\frac{x}{y} \right) \right]metres$

 Trick – 6

• In a 100 m race A runs at ‘x’ km/hr. A gives b a start of y metres and still beats him by ‘t’ seconds, then the speed of B is given by

$\frac{18}{5}\left[ \frac{(100-y)x}{360+xt} \right]km/hr.$
