A. Rs. 600

B. Rs. 800

C. Rs.500

D. Rs.900

Solution(By Examveda Team)

Let the cost of one toy = X.
Then, cost of 18 toys = 18X.
Gain = 3X.
SP of 18 toys = Rs. 16800.
Gain = SP – CP
3X = 16800 – 18X
21X = 16800
X = Rs. 800.

    Selling price of 18 cots -cost price of 18 cots =cost price of 3 cots
    So, selling price of 18 cots =cost price of 21 cots
    Cost price of 21 cots =16800
    Cost price =800
