Question

if 140 is reduced to 112 what per cent is the reduction

Answer 1

Hey !

Solution:

Given that, 140 is reduced to 112. We must find the percentage decrease in the value.

Well the formula to be used here is :

Reduction % = ( Reduction / Original Value ) * 100

=> Reduction = 140 - 112 = 28

Hence Reduction % = ( 28 / 140 ) * 100

=> Reduction % = 2800 / 140

=> Reduction % = 20 %

Hence the value has reduced 20 % from it's original value.

Hope my answer helped !

Answer 2

20% is reduction.

Given :

Original amount = 140

Reduced amount = 112

So,

Difference in amount = 140 - 112 =28

To Find :

The reduction %

Solution :

As given,

• Original amount = 140
• Reduced amount = 112
• Difference in amount = 140 - 112 = 28

Now,

Reduction percent = $\bf \dfrac{Change}{Original} \times 100$

So,

Reduction percent :

$\implies \sf \dfrac{28}{140} \times 100$

Reduction percent = 20%

Hence 20% is reduction.
