Answer 1

Answer:

let suppose Virat score = x

then sachin score 30 more than virat = x+30

if virat run increased by 28% and sachin score decreased by 20% then both scores will be equal

x*128/100 = (x+30)*80/100

x*32/25 = (x+30)*4/5

x*32/5= (x+30)*4

32x = 20x+600

12x = 600

x = 50

then sachin score will be x+30 = 80
