Dear student

cost price = price at which table is bought + repairs

c.p.= 850 + 850x1/10
     = 850+85 =935
so, ​​​​​total cost price = Rs.935 

selling price =Rs. 1050

As, S.P. is greater than C.P., the seller is said to have a profit or gain

gain= s.p. - c.p.
       =1050 - 935 
       =115
 

Gain Percentage: (Gain %)

Gain % =		Gain x 100
		C.P.

So, Gain% =   $\frac{115 \times 100}{935}$  = 12.29 %

So, the gain percent is 12.29%
