Here is your solution.. hope it helps
There are 20 cassettes.
Step-by-step explanation:
Given,
Ratio of cassette to compact disc = 10:3
Let,
the number of cassettes = 10x
Number of compact disc = 3x
According to given statement;
the number of cassettes is 10 less than 5 times the number of compact discs.
10x = 5(Number of CD) - 10

Dividing both sides by 5

Number of cassettes= 10x = 10(2) = 20
There are 20 cassettes.
