What is the ratio with which the total sum is shared among three?
a)2:5:7
b)3:4:7
c)3:5:8
d)3:5:7​

Answer 1

Answer:c)3:5:8

*Explanation* : let naveen be n

Let vines be v and let hari be h.

Then :v+n+h=6720

Given: n-840=v.......(1)

H=n+1260.......(2)

From equation (1) & (2)

N+n-840+n+1260=6720

3n=6300

N=2100

V=1260

H=3360

Therefore : V:N:H

=1260:2100:3360

=3:5:8

Hope it is helpful

Answer 2

Answer:

vinod=x

Naveen=x+840

hari=x+840+1260

x+x+840+x+840+1260=6720

3x+2940=6720

3x=6720-2940

x=3780/3

x=1260

so,

vinod=x=1260

Naveen=x+840=2100

hari=x+840+1260=3360

ratio,
