Answer 1

•Answer:

80 more idlis.

•Step-by-step explanation:

→50 students eat 200 idlis.

→1 student eats (200/50=) 4 idlis

→Hence (50+20=) 70 students will eat 4×70 idlis = 280 idlis.

→Hence change in number of idlis= 280-200 = +80 idlis i.e. 80 more idlis.

Answer 2

280

step by step explination

idlies eat by 50 students = 200

idlies eat by 1 student = 200/50

students more added = 50+20 =70

idlies eat by 70 students = 4*70

= 280
