On this Nithra Jobs site, we have given article bout races and games with formulas for better understanding which helps in improving one's aptitude and ultimately help in clearing exams. To know about the races and games formulas refer this link.

1. A can run 40 m while B runs 80 m. In a kilometre race B beats A by?

Answer: 500 m

Explanation:

Given data,

1 Kilo meter = 1000 m

When B runs 80 m, A runs 40 m

When B runs 1000 m, A runs ( 40 / 80 ) * 1000 m

= ( 40 * 1000 ) / 80

= 1000 / 2

= 500 m

B beats A = ( 1000 - 500 )

= 500 m

B beats A by 500 m.

2. At a game of billiards, A can give B 15 points in 40 and A can give C to 20 points in 40. How many points can B give C in a game of 50?

Answer: 10 points

Explanation:

Given data,

A can give B 15 points in 40,

Then, A : B = 40 : ( 40 - 15 ) = 40 : 25

A can give C to 20 points in 40, Then, A : C = 40 : ( 40 - 20 ) = 40 : 20

To find the number of points can B give C in a game of 50.

Then, B / C = [ ( B / A ) * ( A / C ) ]

= [ ( 25 / 40 ) * ( 40 / 20 ) ]

= 25 / 20

= ( 25 * 2 ) / ( 20 * 2 ) [ * by 2, to find the number of points given in a game of 50 ]

= 50 / 40

= 50 : 40

Hence, B can give C ( 50 - 10 ) points = 10 points

B can give C 10 points in a game of 50.

3. A runs 5 times as fast as B. If A gives B a start of 88 m, how far must the winning post be so that A and B might reach it at the same time?

Answer: 110 m

Explanation:

Ratio of the speeds of A and B = 5 : 1

Thus, in race of 5 m, A gains 4 m over B,

4 m are gained by A in a race of 5 m,

88 m will be gained by A in race of ( 5 / 4 ) * 88

= 110 m

Winning post is 110 m away from the starting point.

4. In a 200 m race A beats B by 12.5 m or 8 seconds. B's time over the course is?

Answer: 128 seconds

Explanation:

Given data,

B runs ( 25 / 2 ) m in 8 seconds [ since ( 25 / 2 ) = 12.5]

B covers 200 m = ( 8 * 200 * ( 2 / 25 ) )

= 8 * 8 * 2

= 128 sec

B's time over the course = 128 sec.

5. In a game of 100 points, A can give B 20 points and C 44 points. Then, B can give C?

Answer: 30 points

Explanation:

Given data,

A can give B 20 points

Then, A : B = 100 : ( 100 - 20 )

= 100 : 80

A can give C 44 points

Then, A : C = 100 : ( 100 - 44 )

= 100 : 56

To find the number of points can B give C in a game of 100

Then, B / C = [ ( B / A ) * ( A / C ) ]

= [ ( 80 / 100 ) * ( 100 / 56 ) ]

= 80 / 56 = 10 / 7

= 10 * 10 / 7 * 10 [ * by 10, to find the number of points given in a game of 100 ]

= 100 / 70

= 100 : 70

Hence, B can give C ( 100 - 70 ) points = 30 points

B can give C 30 points in a game of 100.

Problems for practice:

1. In a 100 m race, A can give B 10 m and C 28 m. In the same race B can give C:

2. A and B take part in 100 m race. A run at 5 kmph. A gives B a start of 8 m and still beats him by 8 seconds. The speed of B is:

3. In a game of 100 points, A can give B 20 points and C 28 points. Then, B can give C:

4. A can run 22.5 m while B runs 25 m. In a kilometre race B beats A by:

5. In a 200 metres race A beats B by 35 m or 7 seconds. A's time over the course is:
