Detailed Solution

$\frac{2 (a + b) - a}{a} = 2 a + 2 b = 2 a 2 b = a \frac{1}{f_{2}} = (1.5 - 1) (\frac{2}{40}) f_{2} = 40 f_{m} = - 20 \frac{1}{F} = \frac{1}{f_{m}} - \frac{2}{f_{2}} f = - 10 c m \frac{1}{V} + \frac{1}{u} = \frac{1}{F} a = 5 \frac{1}{2 a} + \frac{1}{- a} = \frac{1}{- 10} b = 2.5$
