Question

price of product is reduced by 30% by what percentage should it be increased to make it 100%​

Answer 1

Answer:

42.86% approx

Step-by-step explanation:

if initial price is Rs 100 and reduced price is Rs 70.

Then to make it 100 again, price should increase by 100*30/70= 300/7 % or 42.86% approx.

Answer 2

Given : Price of product is reduced by 30%

To find : By what percentage should it be increased to make it 100%?

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate required percentage)

Let, the initial price of the product = Rs. 100

After getting reduced by 30% , the price becomes :

= Rs. [100 - (100 × 30%)]

= Rs. [100 - {100 × (30/100)}]

= Rs. (100 - 30)

= Rs. 70

The 100% of the money = Rs. 100

So, with the reduced amount of money (i.e. Rs. 70), we have to add Rs. 30 to get back 100% of the money (i.e. Rs. 100).

[70 + 30 = 100]

Now, we just need to calculate that, what percentage of Rs. 70 is equal to Rs. 30?

So, the required percentage will be :

= 100 × (30/70)

= 42.86% (approx.)

Hence, it should be increased by approximately 42.86% to make it 100%.
