Answer:
Answer is 35
Step-by-step explanation:
After 15 days, 600-180=420.
After 15 days, 600-180=420.Therefore, 600 : 50
After 15 days, 600-180=420.Therefore, 600 : 50 420 : X
Let X represent the number of days.
So now, X. × 50
X. × 50 ----. ----. Or Simply 50/ 600= 1/12
X. × 50 ----. ----. Or Simply 50/ 600= 1/12 420. 600.
No u cross multiply this fraction.
Which is, X × 12= 12X
X × 12= 12X 420 × 1 = 420
U have to let X stand alone.
12X = 420
12X = 420 ------. -------
12X = 420 ------. ------- 12. 12
So now u cancel out, 12 will cancel 12 so X will stand alone.
So now 12 will cancel 420 which means 12 will go into 420, 35times.
Therefore X = 35
Meaning the hostel will feed the rest of the students for 35days.
