Krishna purchased an item for Rs. 16,200 and sold it at the gain of 16%. From that amount he purchased another item and sold it at the loss of 20%. What is his overall gain/ loss ?
Case 1 : C.P. of 1st item = Rs. 16,200
S.P. of 1st item = $$\frac{116}{100} \times 16,200$$
= Rs. 18,792
Case 2 : C.P. of 2nd item = Rs. 18,792
S.P. of 2nd item = $$\frac{80}{100} \times 18,792$$
= Rs. 15,033.60
$$\therefore$$ Overall loss = C.P. - S.P.
= Rs. (16,200 - 15,033.60) = Rs. 1,166.40
