The cost of 1 mango is Rs.5, 1 apple for Rs.1 and for 20 grapes it is Rs.1. I need to buy 100 fruits in Rs.100
Read Solution (Total 1)
-
- 19 Mangoes,1 Apple & 80 Grapes
If number of Mangoes=x, Apple=y & Grapes=z, then
5x+y+(z/20)=100 or 100x+20y+z=2000 ---(i) &
x+y+z=100 ---(ii)
Subtracting (ii) from (i), we have,99x+19y=1900 ---(iii)
From (iii), x=(1900-19y)/99, For y=1, we get x=19, so z=80 - 10 years agoHelpfull: Yes(2) No(0)
