A. 20%

B. $${\text{18}}\frac{2}{9}$$%

C. $${\text{14}}\frac{2}{7}$$%

D. 21%

Answer: Option C

Solution(By Examveda Team)

Total selling price of two bullocks = 8400 + 8400 = 16800
∴ Cost price of first bullock = 8400 × $$\frac{{100}}{{120}}$$ = Rs. 7000
According to the question, there is no profit or loss.
∴ Cost price of second bullock = 16800 – 7000 = Rs. 9800
Selling price of second bullock = Rs. 8400
∴ Loss = 9800 – 8400 = Rs. 1400
∴ Percentage loss on second bullock
$$\eqalign{ & = \frac{{1400}}{{9800}} \times 100\% \cr & = \frac{{100}}{7}\% \cr & = 14\frac{2}{7}\% \cr} $$
