Question

James and Lucas have 14 chocolates each. It is decided that Lucas should have thrice number of chocolates than his friend James. The number of chocolates that James should give to his friend is .

Answer 1

Total no. of chocolates $=14+14=28$.
From multiplication table of 7, we know that $7$ $\times$ $4=28$.
This signifies, $4$ groups of $7$ chocolates will result in $28$.
$4$ groups $=3$ groups $+1$ group.
$4$ groups can be divided in to $3$ groups and $1$ group such that $1^{st}$ group is thrice than that of $2^{nd}$ group.
Here $1^{st}$ group indicates Lucas and $2^{nd}$ group indicates James.
$1$ groups $=1\times 7=7$ chocolates.
Hence James should give $14-7=7$ chocolates to Lucas.
