subratverma   11 years AGO

the total cost of 1 pen and 1 book=60
let the cost of one book and one pen x and y rupess respectively..so
x+y=60
but it is given that the cost of both items in the multiple of 5..
so we will consider only values of x and y which are the multiple of 5..
so te possible outcomes are given below.
x=5,y=55
x=10,y=50

x=15,y=45

x=20,y=40

x=25,y=35

x=30,y=30

x=35,y=25

x=40,y=20

x=45,y=15

x=50,y=10

x=55,y=5
so the possible outcomes are 11..
so option 7 is correct...thanku..:)

As 1B+1P=60
so possible outcome with non zero cost and multiple of 5 are = 11
and are
5+55 =60
10+50 =60
15+45 =60
20+40 =60
25+35 =60
30+30 =60
35+25 =60

sainath   11 years AGO

let x and y be two positive integers...
5x+5y=60
the possible values for each x and y are (5,55),(10,50),(15,45),(20,40),(25,35),(30,30),(35,25),(40,20),(45,15),(50,10),(55,5)...
those are 11...
so option 7

the possible cost of one book and one pen are,
(5+55) or (10+50) or (15+45) or (20+40) or (25+35) or (25+45) or (30+50) or (35+45) or (40+20) or (45+25) or (55+5).
Therefore Total no. of outcomes are 11

Devendra Marghade   11 years AGO

1 book and 1 pen for Rs 60 can have total 11 non zero cost in multiple of 5 combinations as
Cost(book,pen)=(5,55)(10,50)(15,45)(20,40)(25,35)(30,30)(35,25)(40,20)(45,15)(50,10)(55,5)

Balakrishnan M   11 years AGO

Possible cost of Pen ={5,10,15,20,25,30,35,40,45,50,55}
Possible cost of Book = {5,10,15,20,25,30,35,40,45,50,55}
Then possible no. of outcomes for the non zero cost of 1 book and 1 pen will be = 11

Narender Bhardwaj   11 years AGO

Given cost of 1 book+1 pen=60 /-
Specify that all the values are multiple of 5 therefore possible outputs are,
5+55=60,
10+50=60,
15+45=60,
20+40=60,
25+35=60,
30+30=60,
35+25=60,
40+20=60,
45+15=60,
50+10=60,
55+5=60,Hence total number of possible outcomes are=10 ans

jomon v j   11 years AGO

let 5x be price of pen and 5y be cost of pen then

5x+5y =60

x+y =12 then possible combination are

1+11 =12
2+10=12
3+9 =12
4+8 =12
5+7 =12
6+6 =12
7+5 =12
8+4=12
9+3=12

there can be such combinations (5,55),(10,50),(15,45),(20,40),(25,35),(30,30)except(30,30)others will be repeated for 2 times because first will be hold either by book or pen.so total(5*2)+1=11
