Question

if Aarushi reads 8 pages everyday she can finish in 15 days . calculate the time she will take to finish the same book if she reads 6 pages everyday​

Answer 1

Answer:

total no. of pages=120

if she reads 6 pages she will take =120/6

20 days

Answer 2

Answer:

20

Step-by-step explanation:

as the no.of pages decreases,the days taken increases

so this is an inverse proportion

here P=no of pages

D=no of days

P$\alpha$1/D

P=k/D(k=constant of proportionality)

8=k/15

k=8*15

k=120

now assuming P=6

P$\alpha$1/D

P=k/D(k=constant of proportionality)

6=120/D

6*D=120

D=120÷6

D=20
