Q1.
a) Rami read Panchatantra Tales during the summer vacation. Kesu read Akbar Birbal, Karadi Tales and Blue Umbrella. Who do you think read more? How many more pages?
Answer
Name of the bookPages in the book
Swami and Friends179
Panchantantra Tales236
Karadi Tales30
Akbar Birbal96
Blue Umbrella90
Adventures of Feluda128
The Wakanda village library list, page 109.

Rami read more, by 20 pages.

Rami: Panchantantra Tales = 236 pages
Kesu: 96 + 30 + 90
96 + 30 = 126
126 + 90 = 216 pages
HTO112690+216
Kesu’s pages: 126 + 90.
HTO23621620
How many more Rami read: 236 − 216.
Why it happens: Kesu read three books but they are all thin ones, so his three books together are still fewer pages than Rami’s one thick book.
Tip: The table on page 109 spells the book as Panchantantra Tales, while the question spells it Panchatantra Tales. Both mean the same book.
Q2.
b) Sumi has read 23 pages of Adventures of Feluda. How many more pages are left to complete the book?
Answer
Name of the bookPages in the book
Swami and Friends179
Panchantantra Tales236
Karadi Tales30
Akbar Birbal96
Blue Umbrella90
Adventures of Feluda128
The Wakanda village library list, page 109.

105 pages are left.

Adventures of Feluda = 128 pages
Read so far = 23 pages
128 − 23 = 105
HTO12823105
The working, written in columns.
Why it happens: The pages of the book are made of two parts — read and not read. Taking the read part away leaves the rest.
Check it yourself: 23 + 105 = 128.
Q3.
c) Jaggu decides to read all the books listed here during his vacation. He has finished reading Swami and Friends, Akbar Birbal and 50 pages of Feluda in 4 weeks. How many more pages does he have to read to finish reading all the books?
Answer
Name of the bookPages in the book
Swami and Friends179
Panchantantra Tales236
Karadi Tales30
Akbar Birbal96
Blue Umbrella90
Adventures of Feluda128
The Wakanda village library list, page 109.

He still has to read 434 pages.

All the books together:
179 + 236 = 415
415 + 30 = 445
445 + 96 = 541
541 + 90 = 631
631 + 128 = 759 pages
Jaggu has already read:
179 + 96 = 275
275 + 50 = 325 pages
HTO759325434
Pages still left: 759 − 325.
Why it happens: We first find the whole pile of pages, then take away the part he has already read.
Check it yourself: 325 + 434 = 759.
