10.58% . this is the answer but they want it 20 characters long lol

Answer 2

Given:

C.P of 20 oranges=₹56

S.P of 12 oranges=₹35

To Find:

Gain or loss%

Solution:

L.C.M of 20 and 12 is$4\times5\times3$

L.C.M=60

Let the number of oranges bought be 60.

C.P of 20 oranges=₹56.

C.P of one orange=₹$\dfrac{56}{20}$

C.P of 60 oranges=₹$\dfrac{56}{20}\times 60$=168.

S.P of 12 oranges=₹35.

S.P O ONE ORANGE=₹$\dfrac{35}{12}$.

S.P of 60 oranges=₹$\dfrac{35}{12}\times60$=₹175.

Therefore,C.P=₹168 and S.P=₹175.

Since S.P is greater than C.P , it is a gain.

Gain=S.P -C.P=₹(175-168)=₹7

Gain%=$\dfrac{gain}{C.P}\times100$.

Gain%=$\dfrac{7}{168}\times100.$

Gain%=$\dfrac{25}{6}$%

Gain%=$4\dfrac{1}{6}%.$%
