Answers
Step-by-step explanation:
Farmers A, B and C are planting rice saplings in a
field. A has planted x saplings, B had planted 5 saplings
less than A and C has planted 5 saplings more than A. (a) How many saplings did B and C plant together?
(b) If the total number of saplings to be planted is 100
less than 4 times what A has planted,express the total
number of saplings to be plant the answer is 355ed using x .
Answer:
population of village = 4000
increased annually % = 5%
time = 2 years
formula = P × R/100 × T
= 4000 × 5/100 × 2
= 40 × 5/1 × 2
= 200/1 × 2
= 400
hence the population increased by 2 years is 400
ANOTHER METHOD :
population of village = 4000
population of village = 4000increased annually % = 5%
population of village = 4000increased annually % = 5%time = 2 years
= 4000/100
= 40
= increased % = 5
for 2 years = 10%
=40 × 10
= 400
hence,the population of the village increased by 2 years ( 5 +5) is 400
