Q. M men agreed to purchase a gift for Rs D. If 3 men dropout, how much more will each have to contribute towards the purchase of gift?
Read Solution (Total 2)
-
- Total price = D
share of 1 person = D/M
after 3 men dropout share would be = D/(M-3)
diff of share = D/M - D/(M-3) = 3D/M(M-3) - 11 years agoHelpfull: Yes(0) No(0)
- total contribution by M men = D
contribution of each = D/M
after 3 men dropout,(M-3)men contribution will be D
now after dropout contribution of each = D/(M-3)
extra contribution by each = D/(M-3)-D/M
=D[1/(M-3)-1/M]
= 3D/M(M-3) - 11 years agoHelpfull: Yes(0) No(0)
