Xvii) The value of m, if 3, 18, m, 42 are in proportion is:a) 6 b) 54 ...
Solution:

Two numbers are said to be in proportion if the ratio of the first two numbers is equal to the ratio of the last two numbers.

Given that 3, 18, m, 42 are in proportion.

So, 3/18 = m/42

Simplifying the above equation, we get:

2/12 = m/42

1/6 = m/42

Cross-multiplying, we get:

m = 42/6 = 7

Therefore, the value of m is 7.

Hence, the correct option is (c) 7.
