Question

a vendor buys oranges at 9 for rupees 10 and sells them at 12 for rupees 16 find his gain percent​

Answer 1

Step-by-step explanation:

C.P OF 9 ORANGES = RS.10

C.POF 1 ORANGES = RS.10/9

S.P OF 12 ORANGES = RS.16

S.P OF 1 ORANGES = RS.16/12

PROFIT = S.P - C.P = 16/12 - 10/9 = RS. 8/36

PROFIT % = PROFIT/C.P X 100

= 8/36 ÷ 10/9 X 100

= 8/36 X 9/10 X 100 = 20%
