Answer:
a)60 students
Step-by-step explanation:
10=X.....(eq.1st)
25=150.....(eq.2nd)
10 out of 25 were carrying lunchbox
Now,
as we compared eq. 1st and 2nd to 150student's
multiplying 150 by 10.
we have,
1,500....( eq 3rd)
25_/1,500 =60.....(divideding 1st and 3rd)
Hence,60 students have brought lunchbox
