Question

there were 250 liters of water in a tank. after drawing water from the tank 175 litres of the water remained .what was the ratio decrease.

Answer 1

Solution :-

→ Total water in Tank = 250 Litres .

→ Remained water in Tank = 175Litre .

→ Drawing water = 250 - 175 = 75 Litre.

So,

→ Decrease Ratio = (Drawing water) / (Total Water) = (75/250) = (3/10) (Ans).

______________________

Tricky Solution :-

→ Decrease Ratio = 1 - {(Remaining water) / (Total Water)}

→ Decrease Ratio = 1 - { 175 / 250 }

→ Decrease Ratio = 1 - (7/10)

→ Decrease Ratio = (10 - 7) / 10

→ Decrease Ratio = (3/10) (Ans.)

Answer 2

Given

• There are 250 liters of water in a tank.
• After drawing water --> 175 liters are remained

To find

Ratio of decrease water

Solution

Amount of water drawing from tank = (Total water - rest water in tank )

= 250-175

= 75

Amount of water drawing from tank is 75

Now Ratio of decreasing water = $\sf\frac{Drawing\:water}{Total\:water}$

=$\frac{75}{250}$

=$\frac{15}{50}$ (minimising )

=$\frac{3}{10}$

Hence the ratios will be$\frac{3}{10}$
