Answer:
1)320 pages
2) Rs 91.5
Step-by-step explanation:
1) Let the total number of pages in the book is x.
On First day, the man reads 3/8th of x pages = 3x/8 pages of the book.
Therefore portion left to read = x-3x/8
=(8x-3x)/8
=5x/8.
On second day the man reads, 4/5th of 5x/8 pages of book= x/2 pages of book.
Therefore according to the given problem, the pages still left to read are:
x-(3x/8+x/2)=40
x-( 3x+4x)
_______ =40
8
(8x-7x)/8=40
x/8=40
x=40*8
x=320
Therefore total pages of the book is 320.
2)Cost of 1 kg mango is Rs 103/4
Cost of 5/2 kg of mangoes is Rs 5/2 * 103/4
= Rs 515/8
Cost of 1 kg grape is Rs 31/2
cost of 7/4 kg of grape is Rs 31/2 * 7/4
= Rs 217/8
Therefore total money Mrs. sharma has spent is Rs(515/8 + 217/8)
= Rs 732/8
= Rs 91.5
