The following bar graph shows the number of males, number of females and total population of four different villages. Find the total number of children in the four villages.
Answer & explanation
Correct answer: option 3
Total population = No. of males + No. of females + No. of children
⇒ No. of children = Total population - No. of males - No. of females
No. of children
Village A = 1500 - 820 - 400 = 280
Village B = 1600 - 1040 - 320 = 240
Village C = 1400 - 760 - 420 = 220
Village D = 1000 - 580 - 300 = 120
Total no. of children = 280 + 240 + 220 + 120 = 860
