Vijay plays a game, wherein he tosses a coin and scores 9 points if heads turns up and 5 points if tails turns up. A total of exactly 182 points is required to win the game. In how many combinations of heads and tails can Vijay win?
Read Solution (Total 8)
-
- 4 combinations are possible...
(8,22),(18,4),(3,31),(13,13) - 12 years agoHelpfull: Yes(24) No(0)
- 18-heads and 4-tails
as 18x9=162(this means 18 times head so the total sum would be this)
and 5x4=20
162+20=182(this is the minimum no that we can get we can also make the relation with more tails 31x5=155
and 9x3=27 so total 31 tails and 3 heads this is quite large )

- 26
13*9+13*5 - 12 years agoHelpfull: Yes(4) No(5)
- 4 SOLUTIONS POSSIBLE:
(3,31) (4,18) (8,22) (13,13) - 12 years agoHelpfull: Yes(2) No(0)
- ans 13 combination (13 heads & 13 tails)
13*9+13*5=182 - 12 years agoHelpfull: Yes(1) No(6)
- what is exact ans plz tell
- 12 years agoHelpfull: Yes(1) No(0)
- combination would be only 3.
(19,4),(4,22),(13,13)... - 12 years agoHelpfull: Yes(0) No(6)
- in terms of points total possible combinations are
(162,20)
117,65
72,110
42,140
27,155
same will be the possibilities for heads and tails in multiples of 9 and 5 respectively
so total 5 combinations are possible - 12 years agoHelpfull: Yes(0) No(5)
