Question

find the total output of a coalmine if after 24% wastage the net output is 68400 quintals

Answer 1

The total output of a coalmine is "90,000".

Step-by-step explanation:

Given,

After 24 % wastage,

∴ Remaining = 100 - 24 = 76 %

Since, 76 % = 68400

Let the total output = x

∴ $\dfrac{76}{100} \times x=68400$

⇒ x = $\dfrac{68400 \times 100}{76}$

⇒ x = 900 × 100 = 90,000

∴ The total output of a coalmine = 90,000

Hence, the total output of a coalmine is "90,000".

Answer 2

The total output of the coalmine is 90000 quintals.

Step-by-step explanation:

Given:

Find the total output of a coalmine if after 24% wastage the net output is 68400 quintals.

Solution:

Wastage =  24%

To find the net product percentage,

= 100% - Wastage

Net product percent = 100% – 24% = 76%

Let the total number be x

$\frac{76}{100} \times x = 68400$

$x = \frac{68400 \times 100}{76}$

x = 90000 .

The total output of the coalmine is 90000 quintals.
