The bar graph given below shows the saving and expenditure of 5 companies J, K, L, M and N.
The average savings of all companies is what percent of the average expenditure of all companies?
Answer & explanation
Correct answer: option 3
Average saving of all the companies = \(\frac{600 + 1600 + 1200 + 600 + 800}{5}\)
= 960
Average of expenditure of all companies = \(\frac{200 + 800 + 600 + 400 + 2000}{5}\)
= \(\frac{4000}{5}\) = 800
Required percentage = \(\frac{960}{800}\) × 100 = 120%
