Formula : .

Train Speed = Distance / Time.

Points to Remember .

To change km/hr into m/sec, we need to multiply it by 5 / 18. .

Example:.

90 km/hr means.

90 x 5 / 18.

= (5 x 5 ).

= 25 m/sec.

And if we need to convert m/sec into km/hr, we multiply it by 18 / 5.

Example:.

90 m/sec means.

90 x 18 / 5.

= ( 18 x 18 ).

= 324 km/hr.

Time taken by a train of length l meters to pass a pole or standing man or a signal post is equal to the time taken by the train to cover l meters.

Time taken by a train of length l meters to pass a stationary object of length b meters is the time taken by the train to cover (l + b) meters.

Profit and loss is the one of major question section in Competitive exams. These formulas will be helpful for your upcoming Exams like PSC, SSC, IBPS and Other Competitive Exams. .

Cost Price(CP) : The Price at which a particular item purchased, is called its Cost Price.

Selling Price (SP): The price at which a particular item is sold, called its Selling Price.

Profit: If Selling Price of an item is more than Cost Price , then vendor is said to have a Profit.

Loss: if Selling Price of an item is less than Cost Price, the vendor said to have a Loss.

Formulas Profit = SP – CP.

Profit % = Profit/(CP)×100.

SP = ((100+Profit% )/100)×CP.

CP = (100/(100+Profit%))×SP.

Loss = CP – SP.

Loss% = Loss/(CP)×100.

SP = ((100-loss%)/100)×CP.

CP = (100/(100-loss%))×SP.
