Question

the cost price of 24 radio sets is $ 18720 find the cost price of one radio set if each radio set costs the same answer 870​

Answer 1

Answer:

$\large \underline{\boxed{\mathsf{Cost \:of\: one\: radio \:= \ 780}}}$

Step-by-step explanation:

$\large \underline{\underline{\textbf{Given that....}}}$

The cost price of 24 radio sets is $ 18720 if all radios cost same then we need to find the cost of one radio..

$\large \underline{\underline{\textbf{Solution..}}}$

Let,

The cost of one radio be 'x'

Number of radio's = 24

Total cost of 24 radio's = $18720

Now we know

Coat of one radio = X

therefore

Cost of 24 radio's would be

$\mathsf{x+x+x+x+x+x ........ 24times}$

Therefore we can write it as

Cost of 24 radio's = 24x

According to question its given that cost of 24 radio's = $18720

Thus we have

$\bold{\mathsf{24x = \ 18720}}$

Now taking 24 to RHS we have

$\implies \mathsf{x = \dfrac{\ 18720}{24}}$

$\implies \mathsf{x = \ 780}$

$\underline{\textbf{Required answer is}}$

$\large \underline{\underline{\boxed{\mathsf{ X = \ 780}}}}$

$\large \mathbf{\bigstar \:\: Points \:to\: remember\:\: \bigstar }$

When we take any term from LHS to RHS or vice-versa the sign ( ie-: + , × , ÷ , - ) on term will be changed to its opposite sign.

Example

(-1) will change to +1

2/3 in this if we take 3 to other side it will change to multiple ...

2×4 in this 4 will change to divide i:- multiply by its reciprocal..

Answer 2

Cost price of 24 radio sets is $18720.

___________ [ GIVEN ]

• We have to find the cost price of one radio.

_____________________________

• Let cost of one radio be M.

So,

Cost of 24 radios will be 24M.

It's like that ..

M + M + M + ........... } upto 24th term (radio)

And cost of 24 radios = $18720

So, cost of M radios = $\dfrac{18720}{24}$

=> $780

______________________________

Cost of 24 radios is $780.

____________ [ ANSWER ]

______________________________

✡ VERIFICATION :

From above calculations we have M = 780

Put value of M in this : 24M = 18720

=> 24(780) = 18720

=> 18720 = 18720

L.H.S. = R.H.S.
