- ans-40
let total mints=x
ruchi take 1/3 n return 4=(x/3-4)
after ruchi take left mint=x-(x/3-4)=2x+12/3
shruti take 1/4 of remng n return 3=(2x+12/12-3)
so shruti hve=(x-12/6)
after shruti rmng mint=(2x+12/3)-(x-12/6)
so rmng=x+4/2
shyli take hlf n return aftr calcu shyli hve=(x-4/4)
after add mints of 3 frnds=3x-28/4
so accrdng ques
equ is 3x-28/4+17=x(total mint)
x=40 ans - 10 years agoHelpfull: Yes(2) No(2)
- 48 is the ri8 answer...since ,let total no. of mints=x ,richa ll have x/3-4
so remaining ll be (x-x/3+4)
sruthi ll take as follos:1/4(2x/3+4)-3
x/6-2
sayali ll take as follows:1/2(x/2+6)-2
x/4+1
x-(total no of mints all three contains)=17
x-(x/3-4+x/6-2+x/4+1)=17
x=48
