Question

A bad workman blames his tool essay
​

Answer 1

Explanation:

C.P of 6 oranges =Rs.20

C.P of 1 orange =620=Rs.3.333

S.P of 4 oranges =Rs.18

S.P of 1 orange =418=Rs.4.5

Here, S.P is greater than C.P, so its gain

Therefore,

Gain =C.PS.P−C.P×100

or, Gain =3.334.5−3.33×100

or, Gain =3.331.17×100

or, Gain =35.135%
