Answer 1

Let cost be x
Sp =Rs 765
Loss =10/100x
Atq
x-10/100x =rs 765
100x-10x/100 =rs 765
90x/100= rs 765
x =765*100/90
x= 850
Now he should sell it at 935 rs

Hola!!! ☺

___________________________________

s.p = ₹765

loss % = 10%

c.p = 100/ 100- loss% * s.p

= 100/ 100-10 * 765

= 100/90*765

= 10/9*765

=850
__________
|C.P. = 850|
--------------------

so, gain = 10%

now,

s.p = 100+gain% / 100 *c.p

= 100+10% /100 * 850

=110/100*850

= 935

__________
|s.p = 935. |
------------------

So, the man should sell for ₹ 935 to get the gain of 10%.
