Question

A vendor buys oranges at 9 for $10 and sells them at 12 for$16 find his gain percent

Answer 1

Answer:

cost of, orange=10/9

sp. 16/12=4/3

Profit = 4/3-10/9=2/9

Profit%=2/9x9/10x 100 = 20%

Answer 2

Answer:

GAIN% = 20%

Step-by-step explanation:

LCM of 9 and 12 =36

let the number of oranges be 36.

C.P of one orange =Rs. (10/9)

C.P of 36 oranges =Rs. (10/9×36)= Rs. 40

S.P of 12 oranges =Rs.16

S.P of 1 orange =Rs.(16/12)

S.P of 36 oranges = Rs.(16/12×36)=Rs 48

Therefore, C.P =Rs.40 AND S.P =Rs.48

Since (S.P)< ( C.P), the vendor gains.

GAIN= Rs. 48-40

=Rs. 8

Gain % = (gain/C.P ×100)%

Gain %= (8/40×100)%= 20%

GAIN%= 20%
