Question

Aman's expense is 30% more than vimal's expense and vimal's expense is 10% less than raman's expense. if the sum of their expenses is ₹ 6447, then what would be the aman's expense?

Answer 1

LET the vimal expense be X
AMAN expense=RS 130 AND raman expense=rs1000/9
ratio of expene of aman,vimal and raman repectively
=130;100;1000/9
=AMAN expense=117*6447/90+117+100
=117*6447*307
=rs.2457

Answer 2

"Aman Expenses = 30 % > Vimal Expense

Vimal Expense = 10 % < Raman Expense

Total Sum of their expense Aman + Vimal + Raman = Rs 6447

LET us assume vimal expense treat as X  

AMAN expense = Rs 130 and raman expense = Rs $\frac { 1000 }{ 9 }$

Proportion of expense of aman, vimal and raman respectively = 130; 100; $\frac { 1000 }{ 9 }$

$\Rightarrow \quad Aman\quad Expense\quad =\quad 117\quad \times \quad \frac { 6447 }{ 90 } \quad +\quad 117\quad +\quad 100$

$=\quad 117\quad \times \quad 6447\quad \times \quad 307$

= Rs 2457"
