Step-by-step explanation:

Ram purchase 6 black and x white ball. The price of Black ball is 5/2 of the price of the white ball. At the time of making the bill clerk made a mistake and interchange the no. of bolls due to this the bill amount in increased by 45%. Find x.​

ANSWER:am ordered for 6 black toys and some brown toys.

Let the price of brown toy = Rs. x

Let the number of brown toys = y

Total price of brown toys = Rs. xy

The price of a black toy is  times that of a brown toy.

Price of a black toy = Rs.

Total price of black toy = Rs.  = Rs. 15x

Total price of black and brown toys = xy + 15x

While making the bill the clerk interchanged the numbers of black and brown toys due to which there was 45% increase in the amount of bill.

Total price of black and brown toys after interchange = 6x +

=> 120x + 50xy = 29xy + 435x

=> 435x - 120x = 50xy - 29xy

=> 315x = 21xy

=> y =  = 15

Hence, the number of brown toys is 15.
