Question

Pooja purchased 110 novels in four days depending upon the requirement of each day for the school library. The price of
one novel is rupees 100. On Tuesday she bought 3 more novels than she bought on Monday,. On Wednesday, she bought
twice the number of novels she bought on Tuesday and on Thursday she bought 1 more than she bought on Monday. If
number of novels she bought on Monday is x, then
(a) What will be the number of novels she bought on Tuesday, Wednesday and Thursday?
(b) Frame an equation for the situation.
(c) Do you read novels? Write any one important aspect of reading novels.

Answer 1

Given, No. of novels bought on Monday is x

Tuesday = x+3

Wednesday = 2(x+3)

Thursday = x+1

Now, x+x+3+2(x+3)+x+1 =110

or, 2x+3+2x+6+x+1=110

or, 5x+10 =110

or, 5x=110-10

or, 5x =100

or, x =100/5 =20

(a) On Tuesday = x+3 = 20+3 =23

On Wednesday = 2(x+3) = 2(20+3)

=2×23 =46

On Thursday = x+1 = 20+1 =21

Answer 2

Answer:

Given, No. of novels bought on Monday

is x

Tuesday = x+3

Wednesday = 2(x+3)

Thursday = x+1

Now, x+x+3+2(x+3)+x+1 =110

or, 2x+3+2x+6+x+1=110

or, 5x+10 =110

or, 5x=110-10

or, 5x =100

or, x =100/5 =20

(a) On Tuesday = x+3 = 20+3 =23

On Wednesday = 2(x+3) = 2(20+3) =

=2x23 =46

On Thursday = x+1 = 20+1 =21
