Preferred Mode of Payment by Age Group

Study the 100% stacked bar graph below. It shows, for each age group, the percent of respondents who prefer cash, e-wallet or card payments. The number of respondents in each age group is given as n. Use it to answer the questions that follow.

How many respondents in ALL age groups combined prefer cash?

  1. 145
  2. 380
  3. 415
  4. 395

Answer

D. 395

Solution

18–30: 30% of 400 = 120; 31–45: 45% of 300 = 135; 46–60: 70% of 200 = 140. Total = 395. (Adding the percents, 145, is wrong.)
