Số sách tham khảo là:

   300 \(.\) \(\dfrac{7}{20}\) = 105 (quyển)

Số truyện là:

   300 - (105 + 75) = 120 (quyển)

Có điểm N nằm giữa 2 điểm P và Q

nên PN + NQ = PQ

\(\Rightarrow\) NQ = PQ - PN

Mà PQ = 10cm

      PN = 3cm

\(\Rightarrow\) NQ = 10 - 3

     NQ = 7cm

Có I là trung điểm của đoạn thẳng NQ

\(\Rightarrow\) NI = IQ = \(\dfrac{1}{2}\) NQ

Mà NQ = 7cm

\(\Rightarrow\) NI = IQ = \(\dfrac{1}{2}\) x 7

     NI = IQ = 3,5cm

Vậy IQ = 3,5cm
