590600616585620Option C

2๐๐ โ 2๐ = 90

๐ = 21 ๐๐

Radius of circle B=14 cm

Area of circle B= 616 cm^2 - There are 40 children in a class in which boys are 4 more than the girls. Average weight of all the students is 42.5 kg and the average weight of all the girls is 48 kg then find the average weight of all the boys.
5042303848Option D

x+4+x=40

x=18

Total weight of all students = 40ร 42.5 = 1700๐๐

Total weight of girls=18ร 48 = 864 ๐๐

weight of all boys=1700 โ 864 = 836 kg

Average weight of all boys = 836/22 =38 kg - Ratio of present ages of two persons A and B is 3:2 and after four years ratio of their age (B : A) become 7:10. Then find the present age of B?
3028322429Option D
