Answer 1

Answer:

total number of boys =490.

Step-by-step explanation:

the.% of boys from Maharashtra =20%

the%of boys from Bombay = 30 %

so, the% of boys who are from Maharashtra but not from Bombay =(30% -20%)=10%

Let the total number of boys be x

so,

10x/100 =49

or, x= 490

so, the total number of boys = 490
