Question

john read 25% of his book on wednesday, 35% on thursday and remaining 120 pages on friday how many pages did john read altogether on wednesday and thursday

Answer 1

Answer:

I suggest to solve this problem with backward tehnique. First you must 1–3/7= 4/7 , in the other words if you read 3 seventh of book,4 seventh will be unread.

Next day she read 1/4 of remainder. U do same thing like before. 4/7−1/4=9/28

Afer this u realize that she left 75 pages unread and those 75 pages are 9 twenty eights of book 9/28=75 pages

Now u add 9/28+9/28+9/28=27/28 or in the pages 75+75+75=225 pages.

Final step is to divede 28 :9=3.111 this is how much times u need to add 75. Because we already add 3 times we nees to add o.111 time 0.111×75=8.325 add those 8 pages to the rest and u will ger 233.325 pages what ia the result.

Answer 2

Step-by-step explanation:

100% - 35% - 25%

= 40%

40% of x = 120

40/100 x = 120

40x = 12000

x = 12000/40

x= 300 Pages

Hey, Answer => 300 Pages
