If $A: B = 2: 3$ and $B: C = 3: 7,$ then $A + B : B + C : C + A$ is

₹ $1050$ are divided among $A, B$ and $C$ in such a way that the share of $A$ is $\frac{2}{5}$ of the combined share of $B$ and $C$. $A$ will get (in ₹):

$A, B$ and $C$ received an amount of ₹ $8400$ and distributed it among themselves in the ratio of $6: 8: 7$ respectively. If they save in the ratio of $3: 2: 4$ respectively and $B$ saves ₹ $400$,then what is the ratio of the expenditures of $A, B$ and $C$ respectively?

The present ages of $A$ and $B$ are in the ratio $5:6$ respectively. After seven years,this ratio becomes $6:7$. Then the present age of $A$ in years is:

$A$ certain amount was to be distributed among $A$,$B$,and $C$ in the ratio $2:3:4$,but was erroneously distributed in the ratio $7:2:5$. As a result of this,$B$ received ₹ $40$ less. What is the actual amount (in ₹)?

Two candles of the same height are lighted at the same time. The first is consumed in $8 \text{ hours}$ and the second in $6 \text{ hours}$. Assuming that each candle burns at a constant rate,in how many hours after being lighted,the ratio between the height of the first and second candles becomes $2:1$?
