CAT 2003 Slot 1 — DILR Question 23
Answer the following question based on the information given below.
Table A below provides data about ages of children in a school. For the age given in the first column, the second column gives the number of children not exceeding that age. For example, first entry indicates that there are 9 children aged 4 years or less. Tables B and C provide data on the heights and weights respectively of the same group of children in a similar format. Assuming that an older child is always taller and weighs more than a younger child, answer the following questions.
âââââââ
What is the number of children of age 9 years or less whose height does not exceed 135 cm?
Answer & solution
- A
48
45
- C
3
- D
Cannot be determined
Number of children of age 9 years or less = 48
Number of children having height of 135 cm or less = 45
âµ The table given is a cumulative frequency table.
∴The lower value is the answer.
∴ 45 is the number of children satisfying both the conditions.
Hence, option (b).
