Answer 1

Answer:

Step-by-step explanation:

Given that,

Profit percent of gopi = 12%

S.P of Ibrahim = Rs. 1330

Loss percent of Ibrahim = 5%

Let the cost price of gopi = X

S.P of Gopi = C.P of Ibrahim = 12%

= 0.12X

Selling price = cost price + profit

⇒

⇒

⇒

∴ S.P of gopi = 1.12X = C.P of Ibrahim

To find the S.P of Ibrahim,

= 0.056X

∴ loss = 0.056X

Selling price = Cost price - loss

= 1.12X – 0.056X

= 1.064X

∴ Selling price of ibrahim = 1.064X

Given, S.P of Ibrahim = Rs. 1330

⇒1.064X = 1330

⇒

X = 1250

∴ The cost price of gopi is Rs. 1250

Answer 2

Answer:

1250 rs

Step-by-step explanation:

Let gopi buy the watch at x rupees

C.P.=x

S.P.=x+12%of x

=112x/100=28x/25

so,28x/25=CP for Ibrahim

SP=28x/25-5%of 28x/25

=28x/25-28x/500

=560x-28x/500

=532x/500

=133x/125

=CP of john=1330

133x/125=1330

x=1330×125/133

x=1250
