Answer 1

${\bold{\sf{\underline{Understanding \: the \: question}}}}$

• ➦ This question says that Juhi sold a washing machine for Rupees 27,000. Now this question says that there is a lost of 10% to her on solding machine on that price. Now we have to find the Cost price of the machine.

${\bold{\sf{\underline{Given \: that}}}}$

• ➦ Selling price of washing machine = 27,000 Rupees.

• ➦ There is a loss of 10 % on SP

${\bold{\sf{\underline{To \: find}}}}$

• ➦ CP of the washing machine.

${\bold{\sf{\underline{Solution}}}}$

• ➦ CP of the washing machine = Rupees 30,000

${\bold{\sf{\underline{Using \: concepts\: (atq)}}}}$

➦ Total loss formula

➦ SP finding formula

${\bold{\sf{\underline{Using \: formulas\: (atq)}}}}$

• ➦ Total loss = Loss % of CP

• ➦ SP = CP - loss

${\bold{\sf{\underline{Full \: solution}}}}$

~ Firstly we have to find the Total loss

• ➨ Total loss = Loss % of CP

• ➨ Total loss = 10 % of CP

• ➨ Total loss = 10 % × CP

• ➨ Total loss = 10 × CP / 100

Cancelling 0 by 0:-

• ➨ Total loss = CP/10

~ Seeming SP:-

• ➨ SP = CP - lost

• ➨ SP = CP - CP / 10

Taking LCM:-

• ➨ SP = 10 CP - CP / 10

• ➨ SP = 10 CP - 1 CP / 10

• ➨ SP = 9CP / 10

~ Now finding CP ( atq ! )

➨ Finded SP = Given SP

• ➨ 9 CP / 10 = 27,000

Cross multiplying the digits:-

• ➨ CP = 27,000 × 10 / 9

• ➨ CP = 2,70,000 / 9

• ➨ CP = 30,000 Rupees

• Henceforth, the CP of washing machine is Rupees 30,000
