-
- Let x be amount with nephew then with daughter 4x and with son 5x
as,there are 5 sons,4 daughters, 2 nephews the amount is share in ratio
5*5x:4*4x:2*2x i.e., 25:16:2
total amount is 8600, total parts is 43(it is sum of ratios 25,16,2)
so value of x is 8600/43=200
the share of daughter is (16*200)/4

- Let each nephew receive x
then each daughter receive 4x
and each son receive 5x
2x+4*4x+5*5x=8600
x=200
each daughter receive 4*200=800;

- let the amount of money divided among is xRs for son,y for daughter,z for nephew..
now for 5 sons,4 daughters,2 nephews we have 5x,4x,2x resp...
now form the equation as...5x+4y+2z=8600
and the conditions implied on them will be...y=4z,x=5z
now place the values in the equation and get the value of z through it.hance calculate the value of y which is required here...

- As given:-
1 daughter=4 times as one nephew
4 daughter=4*4=16
1 son=5 times as one nephew
5 son=5*5=25
ratio is 25:16:2 (2 nephew)
daughter receive=16/(25+16+2)*8600=3200
4 daughter receives =3200
1 daughter receive=3200/4=800

- let share of 1 daughter be Rs. x.
then the share for 4 daughters : 4x
and as the question says: Daughter = 4(Nephew)
Son= 5( nephew)
therefore,
ratio of all the three : 1 son : 1 daughter: 1 nephew= 5x/4 : x : x/4
now ratio of 5 son: 4 daughter: 2 nephew=25x/4 : 4x : x/4=25x : 16x : 2x
therefore, share of 4 daughters (16x/43x) * 8600= 3200
share of 1 daughter = 3200/ 4 = rs. 800. - 8 years agoHelpfull: Yes(0) No(0)
- d=4n
s=5n
2n+4d+5s=2n+4*4n+5*5n=43n
43n=8600 =>n=200
4d=16n
=>4d=16*200
=> d=800
