Read Solution (Total 5)
-
- say she has bought x amount of shoestrings
pin=4x
handkerchiefs=8x
She paid each item with their count as each piece's cost
so cost of shoestring=x*x
pin=4x*4x
handkerchiefs=8x*8x
so x*x+4x*4x+8x*8x=3.24 =324Poisa
x*x=324/81
x=2
handkerchiefs she bought=8*x=16
- 10 years agoHelpfull: Yes(21) No(0)
- x*x+4x*4x+8x*8x=3.24
81x^2=3.24
x=2
handkerchiefs=2*8=16 - 10 years agoHelpfull: Yes(16) No(5)
- x+4x+8x=3.24
x=.249
handkerchiefs=8*.249=1.992
pins=4*.249=0.996
shoestrings=0.249
adding this we get,1.992+0.996+0.249=3.237 i.e 3.24(appx)
Hence She bought 8 hankerchiefs - 10 years agoHelpfull: Yes(2) No(5)
- let she bought x shoesstring
then pins=4x
handkerchiefs=8x
x+4x+8x=3.24
x=.249
if 13*.249=3.237 which is approx=3.24
Hence ans should be 13 - 10 years agoHelpfull: Yes(1) No(7)
