(a) 306 (b) 765 (c) 700 (d) 510
Read Solution (Total 39)
-
- 10+15+6=31
1581/31=51
so B's share=15*51
=765
A's share =10*51
=510
C's share =6*51
=306

- ans-b
b's share =1581*(15/(10+15+6))=765 - 10 years agoHelpfull: Yes(0) No(0)
- B.765...10x+15x+6x=1581
x=51..
B share = 51*15
=765 - 10 years agoHelpfull: Yes(0) No(0)
- Ans:B 765
given that 31 parts value is 1581
then 15 parts value is-------(1581*15)/31=765 - 10 years agoHelpfull: Yes(0) No(1)
- The share of B is:
(6x/31x/)*1581=765 - 10 years agoHelpfull: Yes(0) No(0)
- answer is b 765
10x+15x+6x=1581
31x=1581
x=51
15x=765 - 10 years agoHelpfull: Yes(0) No(0)
- 10x+15x+6x=1581
31x=1581
x=1581/31
so B's share =15x
=(15*1581)/31=765 - 10 years agoHelpfull: Yes(0) No(0)
- total part=31,each part=1581/31=51,15 part=765 so ans is b
- 10 years agoHelpfull: Yes(0) No(0)
- 765 is the answer
- 10 years agoHelpfull: Yes(0) No(0)
- 10x+15x+6x=1581
31x=1581
x=1581/31==51
now b=15*51==765 - 10 years agoHelpfull: Yes(0) No(0)
- (10x+15x+6x)=1581
31x=1581
x=51
15x=15*51=765 - 10 years agoHelpfull: Yes(0) No(0)
- the share of B =(1581x15/31)=765

- 1581*15/31=765
- 10 years agoHelpfull: Yes(0) No(0)
- (b) 765
add all three and divide it by 1581
now take B's ratio that is 15 and multiply it by the answer of division
- 10 years agoHelpfull: Yes(0) No(0)
- 1581 is divided into 31(10+15+6)parts
each part is 51.
hence b contain 15*51=765 share - 10 years agoHelpfull: Yes(0) No(0)
- 10+15+6=31
1581/31=51
so B's share =15*51=765
B's share=765 - 10 years agoHelpfull: Yes(0) No(0)
- b's proportion will be 15*1581/31=765
- 10 years agoHelpfull: Yes(0) No(0)
- 10+15+6=31
1581/31=51
so B's share=15*51
=765
A's share =10*51
=510
C's share =6*51
=306 - 10 years agoHelpfull: Yes(0) No(0)
- total money=rs 1581
ratio of A:B:C=10:15:6
so share of B=15/31*1581=765 - 10 years agoHelpfull: Yes(0) No(0)
- B=51*15=765
- 10 years agoHelpfull: Yes(0) No(1)
- ratio of b is- 15/(10+12+6)*1581=765
- 10 years agoHelpfull: Yes(0) No(0)
- b is the answer
- 10 years agoHelpfull: Yes(0) No(0)
- 10x+15x+6x=1581
By solving it we get x as 51 then 15*51=765 - 10 years agoHelpfull: Yes(0) No(0)

- share of B is 1581*15/31.
ans : 765 - 9 years agoHelpfull: Yes(0) No(0)
- 31x=1581
x=51
so 15x = 765 - 9 years agoHelpfull: Yes(0) No(0)
- B will be the answer

- let 10x,15x,6x are the ratio of a,b,c respectively,
now we given that a+b+c=1581,
hence we can do -
10x+15x+6x=1581 =>31x=1581 => x=51;
so now the b's share=>
15x=15*51=765 - 9 years agoHelpfull: Yes(0) No(0)
- 1581*15/31= 765
- 9 years agoHelpfull: Yes(0) No(0)
- 765 BECAUSE 15/31(1581)=765
- 9 years agoHelpfull: Yes(0) No(0)
- 1581*15/10+15+6=765
