Q. 16 men went to a restaurant. Fifteen of them paid Rs.80 each and the sixteenth man paid Rs.75 more than the average of all the 16 men. What is the total bill?
Read Solution (Total 5)
-
- Rs 1360
if x is the average bill
16x = 15*80 + x+75
15 x = 1275
x= 85
16x = 1360 - 13 years agoHelpfull: Yes(12) No(0)
- 15 paid Rs.80 each = 15*80 = 1200
total = x
then 16th man would have paid = x-1200
that is = 75+(x/16)
((x/16)=average)
equating these two
x-1200 = 75+(x/16)
x-(x/16)= 1275
15/16x = 1275
x = 1275*16/15
x = 1360 - 13 years agoHelpfull: Yes(2) No(1)
- (16*80)+75=1355
- 12 years agoHelpfull: Yes(0) No(2)
- 1360
Rs 1360
if x is the average bill
16x = 15*80 + x+75
15 x = 1275
x= 85
16x = 1360 - 10 years agoHelpfull: Yes(0) No(1)
- (15*80 + x) /16 +75=x
1200 + x + 16*75 = 16x
1200 + 1200= 15x
x=1360 - 5 years agoHelpfull: Yes(0) No(0)
