Solution

The correct option is D $f = \frac{3}{5}$
$G i v e n, 0.25 (4 f - 3) = 0.05 (10 f - 9) ⟹ \frac{25}{100} (4 f - 3) = \frac{5}{100} (10 f - 9) ⟹ 25 (4 f - 3) = 5 (10 f - 9) [O n m u l t i p l y i n g b o t h s i d e s b y 100] ⟹ 5 (4 f - 3) = 10 f - 9 [] O n d i v i d i n g b o t h s i d e s b y 5] ⟹ 20 f - 15 = 10 f - 9 ⟹ 20 f - 10 f = - 9 + 15 [T r a n s p o s i n g 10 f t o L H S a n d - 15 t o R H S] ⟹ 10 f = 6 ⟹ f = \frac{6}{10} o r \frac{3}{5}$
