Question

The given pie chart shows the favourite cities of a group of people. 66
people like Bangalore. What is the ratio of the number of people whose
favourite city is Bangalore to the number of people whose favourite city is
Delhi?

Answer 1

Step-by-step explanation:

Answer

We know the pie chart=360°.

P+Q+R+S=360°

120°+96°+60°+S=360°

276°+S=360°

∴S=84°

P=100 lakh

∴

360

120

×x=100 lakh.

∴ Total populatino of all 4 cities is 300 lakh, then population in S=

360

84

×300=70 lakh

Answer 2

Answer:

Delhi =90°= 90/360×100=25%

mumbai = 90°=90/360×100=25%

Kolkata = 10%

Bangalore = 100 _ (25+25+10)

100_60=40%

let total people = x

then, 40% of x= 66 (as per the question)

x= 165

number of people like Delhi = 25% of 165

= 41.25 or 41(round off)

Ratio= 66:41
