Question

A pump lift 2400 liters an hourvand its replacnt model can lift 2.5% more how many liters an hour can the new model luft

Answer 1

Answer:

2460 litres an hour can the new model lifts .

Step-by-step explanation:

As given

A pump lift 2400 liters an hourvand its replacnt model can lift 2.5% more.

2.5% is written in the decimal form

$= \frac{2.5}{100}$

= 0.025

Thus

The new model lift more litres = 0.025 × Original amount of water a pump lift .

                                                   = 0.025 × 2400

                                                   = 60 litres

Thus

New model lift litres = Original amount of litres a  pump can lift  + New model lift more litres .

Put all the values in the above

New model lift litres = 2400 + 60

                                 = 2460 litres

Therefore 2460 litres an hour can the new model lifts .

Answer 2

Concept

A percentage is a number of ratio expressed in terms of 100.

Given

Old pump lifts 2400 litres.

New pump lifts 2.5% more than old pump.

To find

How much the new pump lifts?

Explanation

The new model can lift 2.5% more than the old one =2400+2.5%*2400

=2400+25*2400/1000

=2400+60

=2460 litres
