- Inverse Proportionality: M is inversely proportional to N. This means M × N = constant (k).

- Given Values: When M is 20, N is 70. So, k = 20 × 70 = 1400.

- Find M for N = 50: Using the equation M × 50 = 1400, solve for M.

- Calculation: M = 1400 / 50 = 28.

- Option Analysis:

- Option 1: 20 (Incorrect, as calculated M is 28)

- Option 2: 700 (Incorrect, much larger than needed)

- Option 3: 28 (Correct, matches calculated value)

- Option 4: 600 (Incorrect, much larger than needed)
