Question

Difference between the compound interest and simple
interest accrued in two years at 8% per annum is Rs. 128.
What is the principal amount?​

Answer 1

Answer:

Step-by-step explanation:

Principal = (compund interest) if money = $1000

compound interest = 1000*1,08 = 1080

1080*1,08 = 1164.4

Answer 2

Step-by-step explanation:

Answer:

Given :-

A person weight is 60 Newton stands on both feet of area 0.25 square metre.

To Find :-

What is the pressure exerted on one feet.

Formula Used :-

${\red{\boxed{\large{\bold{Pressure =\: \dfrac{Force}{Area}}}}}}$

Solution :-

Given :

Force = 60 N

Area = 0.25 m²

According to the question by using the formula we get,

$⇒ \sf Pressure =\: \dfrac{60 \times 100}{25}$

$⇒ \sf Pressure =\: \dfrac{6000}{25}$

$⇒ \sf Pressure =\: \dfrac{\cancel{6000} \: \: ^{1200}}{\cancel{25} \: \: ^{5}}$

$⇒ \sf Pressure =\: \dfrac{\cancel{1200} \: \: ^{240}}{\cancel{5} \: \: ^{1}}$

$⇒ \sf Pressure =\: \dfrac{240}{1}$

$➠ \sf\bold{\purple{Pressure =\: 240\: N/{m}^{2}}}$

∴ The pressure exerted on one feet is 240 N/m² .
