- ans is 10books with 5rs remaining.
he has 100rs.
he can buy 25 pencils or 15 books
thats a pencil cost is 4 rs.
and book cost is 6.(100/15=6.666 take 6 rs only)
travelling expenses 15%, 100-15=85.
now he has 85 only.
he purchased 5 pencils , one pencil is 4 rs
so 5*4=20.
85-20=65.(now he has).
out of 65 he can purchase 10 books only with remaining of 5rs.
so ans is 10 books and 5 rs remaining - 13 years agoHelpfull: Yes(17) No(29)
- 15 books 100 rupees
therefore 3 books is 20 rupees
and cost of 25 books is 100 rupees
therefore 1 book is 4 rupees
traveling expenses = 15 rupees
5 pencils = 5*4 = 20 rupees
remaining 100 - 35 = 65 rupees
cost of 9 books is 20*3 = 60 rupees
so total 9 books can be purchased and balance amount is 5 rupees - 12 years agoHelpfull: Yes(16) No(3)
- total=100rs
25 pencil=100rs
1 pencil=100/25=4
15 books=100
1 book=100/15=6.66==7
out of 100, 15 rs for travel expences and (5*4=20) for pencils
so balance money=65,
we can purchase 9 books for remaining money.(9*7=63) - 9 years agoHelpfull: Yes(6) No(2)
