Question

if 4500 litres of water is needed to fill 3 same size tanks, then out of 7500 litres of water how many such tanks are filled? ​

Answer 1

If capacity of 3 tanks is 4500 l

Capacity of 1 tank = 4500/3 = 1500 litres

So number of tanks that will be filled with 7500 litres of water = 7500/1500 = 5 tanks

Answer 2

${ \underline{\underline{\bf Question}}}$

If 4500 litres of water is needed to fill 3 same size tanks, then out of 7500 litres of water how many such tanks are filled ?

$\large\tt Answer$

5 tanks of similar capacity can be filled .

$\huge\tt Solution$

It is simply stated that 4500 Litres of water can filled up 3 tanks of similar size.

This means to fill up a single tank , 1500 Litres of water is required.

or it can be understand like 1500 litres of water fill up 1 tank

Therefore, 1 litre of water can fill up (1/1500) of that tank.

So , 7500 litres of tank can fill up (7500/1500)

of tank i.e , 5 tanks of similar size.

Below shown Unitary Method for the same.

$: \implies \sf4500 \: litres = 3 \: tanks \\ : \implies \sf 1 \: tank = \dfrac{4500}{3} = 1500 \: litres \\ : \implies \sf 1 \: litre = \dfrac{1}{1500} tank \\ \\ : \implies \sf7500 \: litres = \cancel\dfrac{7500}{1500} = \red{5 \: tanks}$

Thankyou
