Question

Gopi sold a watch to ibrahim at 12% gain and lbrahim sold it to john loss of 5% if john pay 1330 then find how much did Gopi sold it for

Answer 1

Let Cp of watch for gopi is X Rs

So sp = cp*(100+profit%)/100

= x*112/100

Sp of watch for gopi is equal to Cp of watch for ibrahim

So Cp of watch for Ibrahim =

112x/100rs

Ibrahim so it to John at loss of 5%

So, sp of watch for Ibrahim =

112x/100*95/100

Which is equal to Cp of watch for john

And in question john pay for watch is 1330 Rs

So, 112x*95/10000=1330

X = 1250 Rs

Gopi sold it for = 1250*112/100

=1400 Rs
