Question

Parvinder sold a watch at a loss of 5% if he had sold that was for this 27 more he would have gained 7% find the cost price of the watch​

Answer 1

Let the cost price= Rs x

1)

loss=l=5%

selling price(s1)=x(100-l%)/100

=x(100-5)/100

=95x/100-----(1)

2)

gain (g)=7%

selling price(s2)= x(100+g)/100

= x(100+7)/100

=107x/100-----(2)

but

(2) - (1)=27

107x/100 - 95x/100=27

12x/100=27

x=27*100/12

after cancellation

x=225

therefore

cost price=Rs225

hope it helps you.......

Answer 2

The cost price is Rs.225.

Step-by-step explanation:

Since we have given that

There is a Loss of 5%

if he had sold that was for this 27 more he would have gained 7%.

Let the cost price be 'x'.

According to question,

$\dfrac{107}{100}x-\dfrac{95}{100}x=27\\\\1.07x-0.95x=27\\\\0.12x=27\\\\x=\dfrac{27}{0.12}\\\\x=225$

Hence, the cost price is Rs.225.
