Ma'rifatdagi pulning 1/2 qismi Jamiladagi pulning 3/4 qismiga teng. Jamilaning puli 64000 so'm.

a) Ma'rifat va Jamiladagi pulning nisbati: Ma'rifat puli = (3/4) * Jamilaning puli = (3/4) * 64000 = 48000 so'm. Nisbat: Ma'rifat : Jamilaning = 48000 : 64000 = 3:4.

b) Ma'rifatning puli: Ma'rifatning puli = (1/2) * Jamilaning puli = (1/2) * 64000 = 32000 so'm. Bu noto'g'ri, chunki Ma'rifat pulining 1/2 qismi Jamilaning pulining 3/4 qismiga teng. Shuning uchun, Ma'rifatning puli = (3/4) / (1/2) * Jamilaning puli = (3/4) * 2 * 64000 = 1.5 * 64000 = 96000 so'm.
