Question

Three different types of balls priced at 25, 18 and
13 per piece are displayed in three different boxes
by a trader. Mr. Paul bought from this shop all three
types of balls spending a total sum of 1768. The
numbers of the balls he bought, taken in the order in
which the prices are mentioned above, are in the
ratio 5:4:3. How many balls of the costliest variety
did he buy?​

Answer 1

(5x*25)+(4x*18)+(3x*13)=1768

125x+72x+39x=1768

236x=1768

x=7.49

hence ..uh can find different prices.
