An employee may claim Rs.7 for each km when he travels by taxi and Rs.6 for each km when he drives his own car. If in one week he claimed Rs. 595 for travelling km. How many kms did he travels by taxi?
a.55
b.65
c.62
d.70
Read Solution (Total 11)
-
- let no of km travelled by Texi = x km
let no of km travelled by Car = y km
According to the question
7x + 6y = 595
by hit and trial method putting x=55 we can get the value for y.
no any other choice will be suit on the equation....
so answer will be 55(option a)
- 10 years agoHelpfull: Yes(36) No(3)
- ans will be 55.
as 7x+6y=595
by hit and trial method putting x=55 we can get the value for y.
no any other choice. - 10 years agoHelpfull: Yes(2) No(3)
- since its total cost is 595
and 6 multiples have never 5 in ones place so taxi distance must be multiple of 5 so c & d option removed
since, 7*65= 455
595-455=140,
140/6 =23.3333 not possible
7*55=385
595-385=210
210/6=35
so correct option is (a) - 10 years agoHelpfull: Yes(2) No(0)
- taka a option and try
if he go 55 Km in taxi then=55*7=385
and rest by own car 35 *6=210
add 385+210=595option a
- 10 years agoHelpfull: Yes(1) No(0)
- 7*55+6*35=595
- 10 years agoHelpfull: Yes(0) No(0)
- 7*79 + 6*7 = 595
this can also be the solution to equation??? - 10 years agoHelpfull: Yes(0) No(0)
- hai akanksha, please explain hit & trial method. i can't understand..
- 10 years agoHelpfull: Yes(0) No(0)
- let no of km travelled by Texi = x km
let no of km travelled by Car = y km
According to the question
7x + 6y = 595
by hit and trial method putting x=55 we can get the value for y.
7(55)+6y=595
6y=595-385 y=210/6=35
7(55)+6(35)=595 385+210=595 =595=595
no any other choice will be suit on the equation....
so answer will be 55(option a) - 10 years agoHelpfull: Yes(0) No(0)
- 7x+6y=595
assume 55:7*55=385,it satisfies.(x=55,y=35)
assume 65:7*65=455,y is not a natural number.
assume 62:y is not a natural number.
assume 70:y is not a natural number.
so 55 is correct.... - 10 years agoHelpfull: Yes(0) No(0)
- 55 is the correct answer
- 10 years agoHelpfull: Yes(0) No(0)
- by eliminating the options
ans is - a) 55 - 9 years agoHelpfull: Yes(0) No(0)
