Answer 1

Answer:

A) total no. of students= 750

fee collected from one student= Rs.8500

fee collected from 750 students= 8500* 750

                                                     = 6375000

B) population of city 1= 46342084

population of city 2= 73046546

population of city 3= 92091458

population of city 4= 8924624

total population of these cities= 220,404,712

C) money she has= 700

total cost of doll= 1470.80

money she need t buy the doll= 1470.80-700

                                                  =770.80

D) 30=2×3×5

55=5×11

so take 5 common

so 5×5 =25

E) Perimeter of rectangle=38

2(l+b)=38

2(12+b)=38

24+2b=38

2b=38-24

2b=14

b=14/2

b=7 cm

So breadth is equal to 7cm

F) total no. of marbles= 96525

total no. of people= 45

no. of marbles each one have= 2145
