L.C.M. of 5 and 4 is 20.
So, let he bought 20 apples in both cases.
Case I,
4 apples bought for ₹ 10.
∴ 20 apples bought for ₹ (10 x 5) = ₹ 50. ...(i)

Case II,
5 apples bought for ₹ 10
∴ 20 apples bought for ₹ (10 x 4) = ₹ 40. ...(ii),
From equation (i) and (ii), we get
40 apples bought for ₹ (50 + 40) = ₹ 90.
∴ C.P. of one apple bought = ₹ (90/40) = ₹ 9/4

Case III,
9 apples sold for ₹ 20.
∴ S.P. of one apple = ₹ (20/9).
Since C.P. > S.P. (9/4 > 20/9), it means transaction resulted in loss.

Now, Required loss percent:
