Answer / santhya

let the speed of the car be xkm/h during the up journey...
total distance travelled ill remain same ,ie
7*x=(x+12)*5
or,x=30 km/hr
so distance travld= 7*30=210;

Answer / sankar adhikari

Let the speed is X km per hour
so total journey = 7 x X = 7X

so 7X = 5(X+12)
7X - 5X = 60
X = 30

So, Total journey = 7 x 30 = 210 k.

30 x 7 = 210 k.
(30+12) = 42 x 5 = 210 km.

Answer / prethvi

difference between time is (7-5)=2

12*7*5/2=210

Answer / guest

( a ) 210 km

Answer / suchi teegala

speed = distance / time

let the distance be x
during forward journey ,
time is given as 7hrs
and let the speed be y
therefore , y=x/7
during return journey
since the distance travelled is same in both directions
, here also we will consider the distance as x
now the speed is increased by 12kmph so the speed is y+12
now the time taken is 5 hrs
therefore , y+12=x/5
on solving the both equations
x=7y and
5y+60=x
we get x as 210 km
total distance - distance in forward journey + distance in
return journey
=x+x=2x
i.e., =210+210
=420 km is the answer

1.) In the coming state elections, Bharat Mata Party (BMP) will contest for 77 assembly seats. As BMP's majority vote bank is distributed amongst three communities viz. A, B and C, it will give election tickets only to those workers who belong to these communities. The workers of communities B and C are split into factions. Every faction of community B has 15 workers and that of community C has 25 workers. There were no factions among the workers belonging to community A. If BMP gives a ticket to a worker, it must give tickets to every other worker belonging to the same faction. BMP distinguishes between any two workers only on the basis of their communities. In how many ways can BMP distribute its election tickets giving at least one ticket to each community?
