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

Answer: Option

Explanation:

When B runs 25 m, A runs | 45 | m. |

2 |

When B runs 1000 m, A runs | 45 | x | 1 | x 1000 | m | = 900 m. | |

2 | 25 |

Tell me, if this is correct or not.

The ratio of A: B is 22.5:25.

But the question says if b covers 1000 m what distance the A will cover.

So, 25=1000.

22.5=x.

Cross multiply.

X=1000*22.5/25,

= 900.

So, the difference is 1000-9000.

= 100m.

X=1000*22.5/25,

So, the difference is 1000-9000.

@All.

Please learn to solve problems without using formula then you can remember for a long time.

time is taken by a = 1000/25,

= 40.

40 quantity of time he took to reach destiny in same time how much B have reached?

B distance = 22.5*4 = 900.

Finally distance is a-b = 1000-900 = 100.

It means that A has won the race.

Relative difference =25-22.5=2.5

Thus for 25m---------->2.5

Then for 1000m------------>?

1000*2.5/25 = 100.

Relative difference =25-22.5=2.5

Thus for 25m---------->2.5

Then for 1000m------------>?

1000*2.5/25 = 100.

Thanks @Ravi.

It's very simple calculation.

This is very simple.

A wins 40 times by B (1000/25) in a 1km race.

In each session B lack by 2.5 i.e, (25-22.5).

So totally in a km race, B lack by A is:2.5*40 that is 100.

A wins 40 times by B (1000/25) in a 1km race.

In each session B lack by 2.5 i.e, (25-22.5).

So totally in a km race, B lack by A is:2.5*40 that is 100.

A runs = 22.5m.

B runs = 25m.

B beats A = 25/22.5 = 10/9.

Then, in kilometers race B beat A.

=(9/10)*1000 = 900m.

Hence,1000-900= 100m.

B runs = 25m.

B beats A = 25/22.5 = 10/9.

Then, in kilometers race B beat A.

=(9/10)*1000 = 900m.

Hence,1000-900= 100m.

Can anyone explain how they are calculating with 1/25 or 45/2? I so confuse.

Sana shaikh said:

I understand it clearly.

Ravi: said:

If 25---->2.5.

1000......> (?).

(1000/25)*2.5 = 100.

1000......> (?).

(1000/25)*2.5 = 100.
