Question

Some students planned a picnic. The budget for food was Rs.24. Because 4 students failed to go, the cost of the food for each member got increased by Rs 1. How many students actually went for the picnic?

Answer 1

Step-by-step explanation:

n be the no. of students went for picnic. and x be the cost of food for each member.

According to given conditions:

(n+8)x=480

⇒nx+8x=480⇒nx=480−8x            ...1

and

n(x+10)=480

⇒nx+10n=480

⇒480−8x+10n=480⇒8x=10n⇒x=810n

Put x=810n in (1)

n(810n)=480−4(810n)

10n2+80n−3840=0

n2+8n−384=0

(n+24)(n−16)=0

n=−24,n=16
