Please share the approach:-

20 teams of 5 archers each compete in achery competition.An archer
finishing in kth place contributes k points to his team and there are
no ties.The team that wins will be the one that has the least
score.Given that 1st position team's score is not the same as any
other team,the number of winning scores possible is?
1)236
2)237
3)238
4)239ďťż

Ashish is given 158 rs in one rupee denominations.He has been asked to allocate them into a number of bags the amount required beetween Rs 1 and Rs 158 can be given by handing out certain number of bags without opening them.What is the minimum number of bags requied?


Please tell the approach also...................

x>3

3x - 1 = 4
x = 5/3 not possible

3>=x=> -1

-x + 3 + 2x + 2 = 4
x +5 = 4
x = -1

x
-x -3 - 2x - 1 = 4
-3x = 8
x = -8/3 not possible


so x = -1

lowest winning points = 1+2+3+4+5 = 15

highest winning points = n

n+19*(n+1) = 5050
n ~ 251

so winning score can be from 15 to 251 => 237 scores

Thanks boss.. got it

max no of tiles when rectangles are of size 3 x 2 = 24 x 36 = 864
min no of tiles when rectangles are os size 36 x24 = 2 x 3 = 6
diff = 858
none of these

@gs4890 iift related kya hoga @ 8:30
3699
yes,
x can have following ranges:-
1) for x3-x+2(x+1)=4
x= -1 (possible)
2) for -13-x+2(x+1) = 4
x = -1
3) for x>=3
x-3+2(x+1)=4
x = 5/3 (not possible)
thus x can take value = -1
