Question

ram reads 1/5 of the book If he reads further 40 pages She would have read 7/10 of the book how many pages are left to read​

Answer 1

Step-by-step explanation:

ram reads 1/5 part of the book

4/5 part is remaining

but if he reads more 40 pages then he must have completed 7/10 part of book

converting the statement into equation we get

x/5 +40 =7x/10

7x / 10 -x/5 =40

7x -2x = 400

5x = 400

x= 80

so if he completed 1/5 th part of book ie he completed 80/5 part of book ie 16 pages

the remaining part to read is 4×80/5 = 320 /5 = 64

and if he could have read more 40 pages then he may have completed 56 pages which is 7×80/10 also .

and the pages remaining to read is 3/10 which is 3×80 /10=24 pages remaining
